Narendra Modi's Demonitization "India emerging as New Superpower"

Narendra Modi is being praised all over the world for his courage and vision.  India got Independence in 1947 and now it has been 69 years of Independence and we had 14 Prime Ministers in these 69 years of Independence and Narendra Modi is the prime minister of India showed the courage to curb the black money on such a wide scale.  Our prime minister today needs support of common man to Make India SuperPower.


It is true today common people are standing in line to get cash and no industrialist or politician can be found near the ATM or bank, but I am sure in few days when then lines in banks are over, then common man will be having peaceful sleep and all these people with black money will be in line in the IT departments.  It takes a common man to own a house 20 years of hard working and the rich people owns more than one luxury house around the country which they hardly use to reside in.  Today we common people should support Narendra Modi in his mission of Making India a better place where both common man and rich people are treated equally.  Today common people is paying more tax than others, they are paying tax on their income, they are paying tax on petrol, they are paying tax for each and everything they buy.  If all the black money is curbed by our government then common man no need to pay so much of taxes and more facilities can be provided by the government to the common man.


Please support Narendra Modi, he is working very hard to make India become a Superpower.  He has risked even his position as a Prime Minister with this move where all political parties are against him, he is getting threats from terrorists too.  We should praise his courage.

Named Ranges in Excel


Home>>



A Named Range is way to describe your formulas.  So you do not have to have this in a cell:

=SUM(B2:B4)

You can replace the cell references between the round brackets.  You replace them with a descriptive name, all of your own.  So you could have this, instead:

=SUM(Monthly_Totals)

Behind the Monthly_Totals, though, Excel is hiding the cell references.  We will see how it works, now.


Open up Excel and create the spreadsheet below:


The formula is in cell B5 and just adds up the monthly totals in the B column.

Define a Name

Setting up a Named Range is a two-step process.  You first Define the Name, and then you Apply it.  To Define your name, do this (make sure you have the formula in cell B5):

Highlight the cells B2 to B4 (Not B5), then click the Formulas menu.
Locate the Named cells panel in Excel 2007.  In Excel 2010 and 2013, locate the Defined Names panel instead.
Click Name a Range in Excel 2007 and Define Name in Excel 2010 and 2013.


From the Name a Range menu, click Name a Range (Define Name again in Excel 2010/13):


You will then get the following dialogue box:


Click OK on the New Name dialogue box.  Notice that the Name is our heading of Monthly_Totals.

When you click OK, you will be returned to your spreadsheet.  You would not see anything changed.  But what you have done is to Define a Name.  You can now Apply it.

Apply a Name

To apply your new Name, click in to cell B5 where your formula is, and do this:

On the Named Cells panel, click Name a Range. For Excel 2010/13 users  click Define Name>Define Name
From the menu, select Apply Names
From the Apply Names dialogue box, select the Name you want and click OK:


When you click OK, Excel should remove all those cell references between the round brackets, and replace them with the Name you defined:

In the image above, cell B5 now says:

=SUM(Monthly_Totals)

The cell references have been hidden.  But Excel still knows about them – it is you that can not see them.

Exercise

Study the spreadsheet below, now that we have added another Named Range to cell C5:


Using the same techniques just outlined, create the same Named Range as in our image above.  Again, the formula we have used is just a SUM formula:

=SUM(C2:C4)

You need to start with this, before you Define the Name and Apply it.

Using Named Ranges in Formulas

We will now use two Named Ranges to deduct the tax from our montly totals.

So, to define two new Names, do the following:

Click inside cell B5 to highlight it.
From the Formulas menu bar, locate the Named cells panel, and click Name a Range> (Excel 2007).   In Excel 2010/13, click Define Name> Define Name from the Defined Names panel.
From the New Name dialogue box, click in to the Name textbos at the top and enter Monthly_Result (with the underscore character).
Click OK
Click inside cell C5 and do the same as step 2 above.  This time, however, enter Tax_Result as the Name

You should now have two new Names defined.  We will now Apply these new names.  First, add a new label to your spreadsheet:


Click in to cell B7, next to your new label, and enter the following formula:

=B5-C5

With the formula in place, we can Apply the two new Names we have just defined:

From the Formulas menu bar, locate the Named Cells panel, click Name a Range>Apply Names (Excel 2007).  In Excel 2010/13, click Define Name>Apply Names from the Defined Names panel.
The apply Names dialogue box appears.
Click Monthly_Result to select it
Click on Tax_Result to select it:


Click the OK button

Excel will replace your cell references with the two Names you defined.
Your spreadsheet should look like ours:


If you look at the formula bar, you will see the two Named Ranges.  The formula is easier to read like this.  But it is not terribly easy to set up.  They can be quite useful, though.

MS Excel Goal Seek



HOME


Goal Seek is used to get a particular result when you are not too sure of the starting value.  For example, if the answer is 56, and the first number is 8, what is the second number?  Is it 8 multiplied by 7 or 8 multiplied by 6?  You can use Goal Seek to find out.  We will try that example to get you started, and then have go at a more practical example.


Create the following Excel spreadsheet:


In the spreadsheet above, we know that we want to multiply the number in B1 by the number in B2.  The number in cell B2 is the one we are not too sure of.  The answer is going in cell B3.  Our answer is wrong at the moment, because we has a goal of 56.  To use Goal Seek to get the answer, try the following:

From the Excel menu bar, click on Data.
Locate the Data Tools panel and then What if Analysis item.  From the What if Analysis menu, select Goal Seek.
The following dialogue box appears:


The first thing Excel is looking for is “Set cell.”  This is not very well named.  It means “Which cell contains the Formula that you want Excel to use.”  For us, this is cell B3.  We have the following formula in B3:

= B1 * B2

So enter B3 in to the “Set cell” box, if it is ot already in there.

The “To value” box means “What answer are you looking for?”  For us, this is 56.  So just type 56 in to the “To value” box.

The “By changing cell” is the part you are not sure of.  Excel will be changing this part.  For us, it was cell B2.  We were not sure which number when multiplied by 8 gave the answer 56.  So type B2 in to the box.

Your Goal See dialogue box should look like ours below:


Click OK and Excel will tell you if it has found a solution:


Click OK again, because Excel has found the answer.  Your new spreadsheet will look like this one:


As you can see, Excel has changed cell B2 and replaced the 6 with a 7 – the correct answer.

We will now try a more practical example.

Goal Seek Number Two

Consider this problem:

Your business has a modest profit of 25,000.  You have set yourself a new profit Goal of 35,000.  At the moment, you are selling 1000 items at 25 each.  Assume that you will still sell 1000 items.  The question is to hit your new profit of 35,000, by how much do you have to raise your prices?

Create the spreadsheet below, and we will find a solution with Goal Seek.


The spreadsheet is split in to two:  Current sales and future sales.  We will changing the Future sales with Goal Seek.  But for now, enter the same values for both sections.  The formula to enter for B4 is this:

=B2 * B3

And the formula to enter for E4 is this:

=E2 * E3

The current price per item is 25.00.  We want to change this with Goal Seek, because our prices will be going up to hit our new profits of 35,000, So try this:

From the Excel menu bar, click on Data
Locate the Data tools panel and the What if Analysis item.  From the What if Analysis menu, select Goal Seek
The following dialogue box appears:


For “Set cell”, enter E4.  This is wehre the formula is.  The “To Value” is what we want our new profits to be.  So enter 35,000.  The “By changing cell” is the part we are not sure of.  For us, this was the price each item needs to be increased by.  This was coming from cell E3 on our spreadsheet.  So enter E3 I the “By changing cell” box.  Your Goal Seek dialogue box should now look like this:



Click OK to see if Excel can find an answer:


Excel is now telling that it has indeed found a solution.  Click OK to see the new version of the spreadsheet:


Our new Price per item is 35.  Excel has also changed the profits cell to 35,000.

MS Excel Scenarios



HOME


Scenarios come under the heading of “What-If Analysis” in Excel.  They are similar to tables in that you are changing values to get new results.  For example, what if I reduce the amount I am spending on food?  How much will I have left then? Scenarios can be saved, so that you can apply them with a quick click of the mouse.

An example of a scenario you might want to create is a family budget.  You can then make changes to individual amounts, like food, clothes, or fuel, and see how these changes affect your overall budget.


We will see they work now, as we tackle a family budget.  So, create the spreadsheet below:


The figure in B12 above is just a SUM function, and is your total debts (=SUM(B3:B10).  The figure in D13 is how much you have left after you deduct all your debts.  In cell D13, then enter =D3 – B12.

With only 46 pounds spending money left each month, clearly some changes have to be made.  We will create a scenario to see what affect the various budges cuts have.

From the top of Excel click the Data menu.
On the Data menu, locate the Data Tools panel.
Click on the What if Analysis item, and select Scenario Manager from the menu:


When you click Scenario Manager, you get the following dialogue box:


We want to create a new scenario.  So click the Add button.  You will then get another dialogue box popping up:


The J22 in the image is just whatever cell you had selected when you brought up the dialogue boxes.  We will change this.  First, type a Name of your Scenario in the Scenario Name box.  Call It Original Budget.

Excel now needs you to enter which cells in your spreadsheet will be changing.  In this first scenario, nothing will be changing (because it is our original).  But we still need to specify which cells will be changing.  Lets try to reduce the Food bill, the clothes bill, and the phone bill.  These are in cells B7 to B9 in our spreadsheet.  So in the Changing Cells box, enter B7:B9.
Do not forget to include the colon in the middle.  But your Add Scenario box should look like this:


Click OK and Excel will ask you for some values:


We do not want any values to change in this first scenario, so just click OK.  You will be taken back to the Scenario Manager box.  It should now look like this:


Now that we have one scenario set up, we can add a second one.  This is where we will enter some new values – our savings.

Click the Add button again.  You will get the Add Scenario dialogue box back up.  Type a new Name, something like Budget two.  The Changing Cells area should already say B7:B9.  So just click OK.

You will be taken to the Scenario Values dialogue box again.  This time, we do want to change the values.  Enter the same ones as in the image below:


These are the new values for our Budget.  Click OK and you will be taken back to the Scenario Manager.  This time, you will have two scenarios to view:


As you can see, we have our Original Budget, and Budget two.  With Budget Two selected, click the Show button at the bottom.  The values in your spreadsheet will change, and the new budget will be calculated.  The image below shows what it looks like in the spreadsheet.



Click on the Original Budget to highlight it.  Then click the Show button.  The first values will be displayed.

Click the Close button on the dialogue box when you are done.

So a Scenario offers you different ways to view a set of figures, and allows you to switch between them quite easily.

How to create a report from a scenario?

Another thing you can do with a scenario is create a report.  To create a report from your scenarios, do the following:

Click on Data from the Excel menu bar
Locate the Data Tools panel
ON the Data tools panel, click What if Analysis
From the Scenario Manager dialogue box, click the summary button to see the following dialogue box:


What you are doing here is selecting cells to go in your report.  To change the cells, click on the spreadsheet.  Click individual cells by holding down the CTRL key on your keyboard, and clicking a cell with your left mouse button.  Select the cells D3, B12, and D13.  If you want to get rid of a highlighted cell, just click inside it again with the CTRL key held down.  Click OK when you have selected the cells.  Excel will then create your Scenario Summary:


All right, it is now terribly easy to read, but it looks pretty enough.  Perhaps it will be enough to convince our family to change their ways.

MS Excel Data Table Part 2


HOME


We will do one more Data Table, just so that you get the hang of things.  This time, we will use a more simple formula than PMT, and we will use Rows instead of Columns.  This is the scenario:

You have 250 items that you want to sell on Ebay.  Your unique selling point in this – All items are only $5 each.  Except, you feel $5 may be a bit expensive for the goods you are selling, what you want to know is how much profit you will make if you reduce your prices to $4.50, how much if you reduce to $4.00, and how much for a reduction to $3.50.  Assume that everything gets sold.

To start creating your table, construct a spreadsheet like the one below.  Make sure that you start on a new sheet.


In cell B1 is the number of items we want to sell (250).  Cell B2 has the original price ($5.00), and the Reductions row has our new values.  Cell B3 has a 0 because there is no reduction for $5.  Row 4 is where our Profits will go.

The formula to work out the profits is simply the Number of Items multiplied by the Price per Item.  So click inside cell B4 and enter the following formula:

=B1 * B2

Your spreadsheet will then look like this:


So, if we manage to sell all our items at $5, we will make $1,250.  We are a bit dubious, though.  Realistically, all our items won’t sell at this price.  Lets use an Excel Data Table to work out how much profit we would make at the other prices.

Again, we put the answer in cell B4 for a reason.  This is because when you want Excel to calculate a Data Table in Rows, the formula must be inserted one Column to the Left of your first new value, and then one Row down.  Our first new value is going in cell C3.  So one column to the left takes us to the B column.  One row down is Row 4.  So the formula goes in cell B4.

Next, click inside cell B3 and highlight to cell E4.  Your spreadsheet should now look like this one:


Excel is going to use our formula in cell B4.  It will then look at the new values on Row 3 (not counting the zero), and then insert the new totals for us.  To create a Data Table then, do the following:
From the Excel menu bar, click on Data.
Locate the Data Tools panel
Click on the “What if analysis” item
Select Data Table from the menu.


Just like last time, you will get the Data Table dialogue box.  The one we want now, though is Row Input cell.  But what is the Input Cell this time?

Ask yourself what you are trying to work out, and what you want Excel to recalculate.  You want to work out the new prices.  The formula you enter was:

=B1 * B2

Excel is going to be changing this formula.  You only need to decide if you want Excel to alter the B1 or the B2.  B1 contains the number of items; B2 contains the price of each item.  Since we are trying to work out the profits, we would get if we change the price, we need Excel to change B2.  So enter B2 for the Row Input cell:


When you click OK, Excel will work out the new profits:


So setting a price of $3.50 per item, you would make $875 profit.  You would make $1000 at $4.00 per item, and $1125 if you sell for $4.50.

MS Excel Data Tables Part 1


HOME


In Excel, a Data Table is a way to see different results by altering an input cell in your formula.  As an example, we are going to alter the interest rate, and see how much a $10,000 loan would cost each month.  The interest rate will be our input cell.  By asking Excel to alter this input, we can quickly see the different monthly payments.  Want to know how much would pay back each month if the interest was 24 percent per year.  But other banks may be offering better deals.  So we will ask Excel to calculate how much we would pay each month if the interest ate was 22 percent a year, 20 percet a year, and 18 percent a year.

The formula needed is– PMT ().  Here it is:

PMT (rate, nper, pv, fv, type)

We only need the first three aguments.  So for us, its just this:

PMT (rate, nper, pv)

Rage means the interest rate.  The second argument, nper, is how many months you have got to pay the loan back.  The third argument, pv, is how much you want to borrow.

Lets make a start then.  On a new spreadsheet, set up the following labels:



So we will put our starting interest rate in cell B3 (rate), our loan length in cell B4 (nper), and our last loan amount in cell B5 (pv).

Enter the following in cells B3 to B5:



So you need to enter 24.00% in cell B3, 60 in cell B4, and $10,000 in cell B5.

We will enter our formula now.  Click inside cell D2 and enter the following:

=PMT(BE/12, B4, -B5)

Cell B3 is the interest rate.  But this is for the entire year.  In the formula, we are dividing whatever is in cell B3 by 12.  This will get us a monthly interest rate.  B4 in the formula is the number of months, which is 60 for us.  B5 has a minus sign before it.  It is a minus figure because it is a debt.

When you press the enter key on your keyboard, Excel should given you an answer of $287.68.

Now that we have our function in place, we can create an Excel Data Table.  First though we need to tell Excel about those other interest rates.  It will use these to work out the new monthly payments.  Remember, Excel is recalculating the PMT function.  So it needs some new values to calculate with.


So enter some new values in cells C3, C4, and C5.  Enter the same ones as in the image below:


We have put the PMT function in cell D2 for a reason.  This is one Row up, and one Column to the right of our first new interst rate of 22%.  The new monthly payments are going to go in cells D3 to D5.  Excel needs the table setting out this way.

So that Excel can work out the new totals, you have to highlight both the new values and the function you are using.

So highlight the cells C2 to D5.  Your spreadsheet should look like this:


As you can see, the cells C2 to D5 are now highlighted.  This includes our new interest rate values in the C column, and our PMT function in cell D2.  We can now creat an Excel Data Table.  This will work out new monthly payments for us.  So do this:

From the Excel menu bar, click on Data
Locate the Data Tools panel
Click on the “Whate if Analysis” item:


When you click on the “What if Analysis” item, you will see the following menu:


Click on Data Table, and you will see this small dialogue box:

 

In the dialogue box, there is only a Row input cell or a Column input cell.  We want Excel to fill downwards, down a column.  So we need the second text box on the dialogue box “Column input cell.”  If we were filling across in rows, we would use the “Row input cell” text box.

So click inside the column input cell box and enter B3:


Click OK.  When you do, Excel will work  out the new monthly payments:



So if we could get an 18 percent interest rate, our monthly payments would be $253.93.

If you click inside any of the cells D3 to D5, then look at the formula bar, you will see this:

{=TABLE(,B3)}

That’s Excel’s way of telling you that a table has been created, based on the input cell B3.

MS Excel Add Error Messages


HOME



Data Validation – Restricting what data go in a cell.

You can also restrict what goes in to a cell on your spreadsheet, and display an error message for your users.  We will do this with our comments column.  If users enter too much test, we will let them know by displaying a suitable error box.  Try the following:

Highlight the E column on your spreadsheet (the comments column).

From the Data Tools panel, click Data Validation to bring up the dialogue box again.


From the Allow list, select Text length:


When you select Text length from the list, you will see three new areas appear:


What we are trying to do is to restrict the amount of text a user can input into any one cell on the Comments column.  We will restrict the text to between 0 and 25 characters.

The first of the new areas (Data) is exactly what we want – Between.  For the minimum textbox, just type a 0 (Zero) in there.  For the maximum box, type 25.  Your dialogue box should then look like this:


To add an error message, click the Error Alert tab at the top of the Data Validation dialogue box:



Make sure there is a tick in the box for “Show error alert after invalid data is entered.”

You have three different Styles to choose from for your error message.  Click the drop down list to see them:


In the Title tex tbox, type some text for the title of your error message.


Now click inside the error message field and type some text for the main body of your error message.  This will tell the user what he or she did wrong.



Click OK on the Data validation dialogue box when you are done.

To test out your new error message, click inside any cell in your Comments Column.  Type a message longer than 25 characters.  Press the enter key on your keyboard and you should see your error message appear:


As you can see, the user is prompted to Retry or Cancel.  But our title (Too many characters) is at the top, our stop symbol is to the left, and our error message is displaying nicely.

Hiding Spreadsheet Data in Excel 2007 to 2013:

The data that went in to our lists does not need to be on show for all to see.  You can hide this text quite easily.

Highlight the columns with your data in it (F, G, and H for us).
Click on the Home tab from the top of Excel.
Locate the cells panel.
On the cells panel, click on Format.
You will see the following menu:


Move your mouse down to Hide and Unhide and you will see a sub menu appear:


Click on Hide columns from the Sub menu.  Excel will hid the columns you selected:


In the spreadsheet above, the columns F to H are no longer visible.

To get them back again, highlight the columns E and I.  From the same submenu, click Unhide Columns.
