Railway Budget 2016-2017

Railway Minister Suresh Prabhu presented his second rail budget this year. He kept the fares unchanged.  In his budget speech, he said that for this budget he owes its inspiration to vision of PM Modi who said: "My vision is to make railways backbone of India’s progress & economic development."

He outlined the 3 pillars of strategy - raise new revenues, raise productivity and efficiency and revamp the processes. He also said that the Core objective is to become engine of economic growth, create employment and provide customer service.

So now let’s see what Mr. Prabhu had for the citizens of India. Here are the highlights of the Rail Budget 2016:

[Data Interpretation-3] Calculation Techniques

In this article you will learn some calculation techniques to solve questions quickly, which may look difficult to solve in examination due to lot of calculation.I suggest you to read my previous two articles on DI first and then read this article:

Read: [DI-1] How to Calculate Division of two Numbers Quickly?

Read: [DI-2] Percentage Growth/Increase/Decrease

Let us take an Example:

Below Pi-Graphs represent Sales Revenue of a Company XYZ in three segments: Scooter, Motorcycle, and Three Wheeler for year 2012 and 2013.

Based on Graphs above solve Below Questions.

Question 1: By how much percentage sales revenue of Scooter has increased in 2013 w.r.t. 2012.

      a)    27%             B)30.4%         c) 35%           d) 41%

Solution:

Normal Procedure:

STEP-1 Sales Revenue of Scooter in 2012 = 29% of 79311 = 23000.19 ~ 23000

Sales Revenue of Scooter in 2013 = 34% of 88244 = 30002.96 ~ 30003

(Obviously getting above two values requires lot of Calculation)

STEP-2 % increase in Sales Revenue of scooter

= (Sales Revenue In 2013 – Sales revenue in 2012)*100/ Sales revenue in 2012

= (30003 – 23000) * 100 / 23000 = 30.44 %

                                          OR

Revenue has become 30003 from 23000 so we can also use our M.F. method to calculate % increase.

M.F. = Final Value/ Initial Value = 30003/23000 = 30000/23000 = 30/23 = 1.304

So Percentage Increase = (1.304 -1) *100 = 30.4%

Note: Here Calculation of Step 1 is time consuming. Let us see how we can solve this question quickly.

Alternate Approach:

Do not calculate Step 1

Directly Write:

M.F. = Final Value / Initial Value = 34% of 88244 / 29% of 79311

                                                    = (34/29) * 882/793           (Approximation)

34/29 === > 35/30 = 1.17

882/793 == > 890/800 = 1.11    (Using Division Technique)       

M.F. = 1.17 X 1.11 ~ 1.298 ~ 1.3      [ For Quick Calculation 1.11 = 1+0.1+0.01
                                                   => 1.17 x 1.11 = 1.17 + .117 + 0.0117 = 1.2987 ]

 If M.F. is 1.3 == > % increase will be 30%    Hence option B is correct                                       

Question 2: By how much percentage sales revenue of Motorcycle has changed in 2013 w.r.t. 2012.

      a)    4.7% decrease         B) 4.7% increase         c) 9.4% increase           d) 9.4% decrease

Solution:

M.F. = Final Value/ Initial Value = 48% of 88244 / 56% of 79311

                                                  = (48/56) * (882/793)

                                                  = 6/7 * 882/793

                                                  = 0.86 * 1.1

                                                  = 0.946

Percentage Decrease = (1 – M.F.) * 100 = (1-0.946) *100 = 5.4%

(We got 5.4% since we have used lot of approximation.)

Closest option is A) hence option A is correct.

Question 3: By how much percentage sales revenue of Three Wheeler has increased in 2013 w.r.t. 2012.

       a)    29.5%         B) 33.5%         c) 37.5%           d) 41.5%

Solution:

M.F. = Final Value/ Initial Value = 18% of 88244 / 15% of 79311

                                                  = (18/15) * (882/793)

                                                  = 1.2*1.1

                                                  = 1.32

Percentage Increase = (M.F.-1) * 100 = (1.32-1) *100 = 32%

Closest option is B. Hence option B is correct.

[Data Interpretation-2] Calculating Percentage Growth/Increase/Decrease

In this article you will learn how to calculate Percentage Growth/Increase/Decrease in Data Interpretation Questions. Here I will explain how to use concept of Multiplying Factor for solving Percentage Growth, Increase/Decrease questions quickly. Before moving further first visit the first part of the DI.  [Data Interpretation - 1] How to Calculate Division of two numbers quickly?

Let us take few examples:

Example: XYZ motors limited sold 7000 Scooters in year 2012. If sale of scooter is increases by 10% in year 2013. Calculate no of scooters sold in 2013.

Solution:  Increase in scooter sale = 10% ===è M.F. = 1.1 

Final Value = Initial Value * M.F.

Scooter sales in 2013 = M.F. X 7000 = 1.1 X 7000 = 7700.

Let us understand how to use Multiplying Factor  while solving DI questions.

Example: The below Graph represents Bajaj Auto’s sales volume in different segment from year 2010 to 2013.

Question: What is percentage growth in sales volume of scooter in year 2011 w.r.t. 2010.

            a) 9%            b) 10%               c) 15%                  d) 20% 

Solution: 

Normal Procedure:      No. of Scooter Sold in 2010 = 7000

                                       No. of Scooter Sold in 2011 = 7700

% Increase = [(No. of units sold in 2011 - No. of units sold in 2010) / No. of units sold in 2010] * 100

                  

                  = [( 7700 – 7000 ) / 7000] * 100 = [700/7000] * 100 = 10 %.

Using Multiplying Factor Method:

Final Value = Initial Value * M.F.

M.F. = Final Value / Initial Value 

Note: If final Value and initial Values are given you can calculate Multiplying Factor by dividing Final Value and Initial Value. Once you Got Multiplying Factor you can easily tell % increase or % Decrease.

Let us solve above problem using multiplying factor.

M.F. = Final Value/ Initial Value = 7700 / 7000 = 1.1

If Multiplying Factor = 1.1 ==è 10% increase.         ( 1.1-1=0.1*100 = 10 )

(You can do it mentally no need to raise your pen).

Initially it may appear to you that your normal method is also very fast while solving above questions. So, for showing the effectiveness of Multiplying Factor method let us solve another question.

Question: What is percentage change in sales volume of motorcycle in year 2011 w.r.t. 2010.

                        

                      a)    37% Decrease B) 36% Increase c) 31% Decrease  d) 41% Decrease

Solution: Using Multiplying Factor Method:

Final Value = 5570

Initial Value = 8820

Mutiplying Factor = Final Value / Initial Value

                               = 5570 / 8820

                               = 557 / 882

Multiplying Factor = 557/882 = 569/900 = 0.6322

% Decrease = (1-0.6322) * 100 = 36.78 %  

Hence option A] is correct.

Note: Remember That,

% Increase = (M.F. – 1) * 100

% Decrease = (1- M.F.) * 100

Multiplying Factor is a very useful concept while solving percentages, DI, Profit/Loss, CI and SI. I suggest you understand Multiplying Factor well,if you do understand M.F. you can solve all Profit/loss , CI/SI problems without any formula.

[Data Interpretation-3] Calculation Techniques

[Data Interpretation - 1] How to Calculate Division of two numbers quickly?

While solving Data Interpretation questions, you often need to divide two numbers e.g. to calculate percentages, percentage changes etc.which usually consumes time if you use traditional method of division. In this article you will learn how to divide two numbers quickly.

Let us take one question:

Question: Above Graph represents No. of units sold by Bajaj Auto in different segment from 2005 to 2008.

Ques1: In 2005, Scooters sales in volume is how much percentage of total sales.

           a)    53.65 %            b) 46.82%             c) 56.37%                 d) 59.82%

Solution:  In 2005, Scooters= 482

                            Total Sales= Scooters + Mopeds + Three Wheelers

                                              = 482 + 245 + 128

                                               =855

So,   Answer = 482/855 x 100

Ultimately, you are required to perform division to get the answer.

Now, I will discuss how to calculate the value of 482/855.

Step 1: Approximate your denominator to nearest century number. In this case approximate 855 to 900.

Step 2: Calculate approximate value of the given fraction, in this case take numerator 500 and denominator 900. So approximate value of the given fraction will be 5/9.

Step 3: If a fraction x/y is given and you increase/decrease the numerator and denominator in the ratio x : y the value of fraction does not change.

Let us understand it taking an example:

Given ratio: 5/9

If I increase numerator by 5 and denominator by 9 , new fraction = 10/18= 5/9

If I increase numerator by 10 and denominator by 18 , new fraction = 15/27= 5/9

If I increase numerator by 25 and denominator by 45 , new fraction = 30/54= 5/9

If I decrease numerator by 15 and denominator by 27 , new fraction =  -10/-18= 5/9

Step 4: Since we have calculated approximate value of fraction= 5/9.

Above calculation division becomes easy if you make denominator 900. 

482/855= (482+x)/900

Increase in denominator = 900 – 855 = 45

So, if increase in numerator = 25 ;the value of fraction will not change. (since25/45=5/9 as discussed in step 3)

482/855 = (482+25)/(855+45) = 507/900 = 0.5633

So, Answer will be 56.33%

If you use calculator and find the exact value of fraction 482/855= 0.5637.

So, what we calculated using approximation is very close to actual value. If you look at the options, 

You got the answer which is option [C]

So if you practice above method you can calculate any fraction very easily.

Question2: What is percentage increase in sales of scooter in 2008 w.r.t. 2007?

  a)    25%            b) 28%                   c) 31%                 d) 29%

Solution: % increase in sales = (614-476)/476 * 100

                                                 = 138/476 * 100

Approximate value of 138/476 = 150/500 = 3/10 = 0.3/1

138/476 = (138+x)/500 

Increase in denominator = 500 – 476 = 24

Corresponding Increase in Numerator= 24 x 0.3 = 7.2 

So, 138/476 = (138+7.2) / (476+24) = 145.2/500 = 0.2904

Answer = 29.04 % 

Hence option D is correct.

If you use calculator and find out the exact value of 138/476 = 28.99%

So, Practice this method of division which will be very helpful in saving your time In Data Interpretation.
