Directions : Study the following line chart carefully and answer the questions given beside.
 
The following line graph gives the information about the percentage increase in turnover of four companies (Patanjali, Reliance, Airtel, and Accenture) during the year 2012 to 2017 with respect to previous year.
 
1
If at the end of year 2011, the turnover of Patanjali was 25% less than the turnover of Airtel then at the end of 2014, the turnover of Patanjali was how much percent less than the turnover of Airtel? (approximately) 
» Explain it
D
At the end of 2011, the respective ratio of the turnover of Patanjali and Airtel = 3 : 4 (the turnover of Patanjali was 25% less than the turnover of Airtel)

Let us assume that the turnover of Patanjali at the end of 2011 = 3x and the turnover of Airtel at the end of 2011 = 4x

Then, the turnover of Patanjali at the end of 2014

= 3x ×  105  ×  108  ×  112  = approximatley 3.81x
100 100 100

The turnover of Airtel at the end of 2014
= 4x ×  160  ×  180  ×  175  = 20.16x
100 100 100

The reqd. % =  (20.16x – 3.81x) × 100  = approximately 81%
20.16x

Hence, option D is correct.
2
If at the end of 2015, the turnover of Patanjali was 75% of the turnover of Airtel, turnover of Airtel was 60% of the turnover of Accenture and the turnover of Accenture was 80% of the turnover of Reliance. If it is given that the turnover of Reliance at the end of 2015 was $ 1.75 billion. Then what was the sum of the total turnover of all the companies together at the end of 2017? (round off two decimal) 
» Explain it
A
At the end of 2015, Let the turnover of Airtel = 4x then the turnover of Patanjali = 75% of 4x = 3x. turnover of Airtel was 60% of the turnover of Accenture, 60% of accenture’s turnover = 4x
 
Accenture’s turnover = 4x ×  100  =  20x  similarly,
60 3

Reliance’s turnover =  (20x/3) × 100  =  25x
80 3

According to the question,
25x  = 1.75
3

X = 0.21

At the end of 2017,
 
the turnover of airtel = 4x ×  150  ×  125  = 7.5x
100 100

the turnover of Patanjali = 3x ×  164  ×  175  = 8.61x
100 100

the turnover of Accenture =  20x  ×  150  ×  160  = 16x
3 100 100

the turnover of Reliance =  25x  ×  180  ×  175  = 26.25x
3 100 100

Required sum = 7.5x + 8.61x + 16x + 26.25x = 58.36x = 58.36 × 0.21 = 12.2556 billion

Hence, option A is correct.
3
If the total turnover of Patanjali at the end of 2012 was $ 1 billion then find the total turnover of Patanjali at the end of 2017? (round off two decimal) 
» Explain it
C
the total turnover of Patanjali at the end of 2017

= 1 ×  108  ×  112  ×  132  ×  164  ×  175  = $ 4.58 billion approximately
100 100 100 100 100

Hence, option C is correct.
4
At the end of 2012, the respective ratio of the turnover of Patanjali, Reliance, Airtel, and Accenture was 2 : 7 : 4 : 5 then what was the respective ratio of the turnover of all the companies at the end of 2011?
» Explain it
D
Let at the end of 2011, the respective ratio of the turnover of Patanjali, Reliance, Airtel, and Accenture = A : B : C : D

Then, 105% of A = 2x

A =  40x
21

For Reliance, 125% of B = 7x
B =  28x
5

For Airtel,

160% of C = 4x
C =  5x
2

For Accenture,

110% of D = 5x
D =  50x
11

The reqd. ratio =  40x  :  28x  :  5x  :  50x
21 5 2 11

40  :  28  :  5  :  50  =  20  :  14  :  5  :  25
21 5 2 11 21 5 4 11

Hence, option D is correct.
5
Which of the following shows the approximate percentage increase in the turnover of Accenture during the six years? 
» Explain it
B
Let the turnover of Accenture at the end of 2011 = 1 then the turnover of Accenture at the end of 2017

= 1 ×  110  ×  130  ×  125  ×  140  ×  150  ×  160  = 6.006
100 100 100 100 100 100

Reqd. % =  (6 – 1) × 100  = approximately 500%
1

Hence, option B is correct.
