### Quiz

Directions (1-5): Study the following line chart carefully and answer the questions given beside.

The following line graph gives information about the percentage increase in the turnover of four companies (Patanjali, Reliance, Airtel, and Accenture) during the year 2012 to 2017 with respect to the previous year.

1. If at the end of the 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)

A. 40%
B. 60%
C. 51%
D. 81%
E. 85%

Explanation:
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 × $$\frac{105}{100}$$ × $$\frac{108}{100}$$ × $$\frac{112}{100}$$ = approximatley 3.81x

The turnover of Airtel at the end of 2014

= 4x × $$\frac{160}{100}$$ × $$\frac{180}{100}$$ × $$\frac{175}{100}$$ = 20.16x

The reqd. % = $$\frac{(20.16x – 3.81x) }{20.16x}$$ × 100 = approximately 81%

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 $1.75 billion. Then what was the sum of the total turnover of all the companies together at the end of 2017? (round off two decimal) A.$ 12.25 billion
B. $14.21 billion C.$ 7.48 billion
D. $9.64 billion E.$ 6.14 billion

Explanation:
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 × $$\frac{100 }{60}$$ = $$\frac{20x }{3}$$ similarly,

Reliance’s turnover = ( $$\frac{\frac{20x}{3}}{80}$$ ) × 100 = $$\frac{25x }{3}$$

According to the question,

25x = $$\frac{1.75 }{3}$$

X = 0.21

At the end of 2017,

the turnover of airtel = 4x × $$\frac{150 }{100}$$ × $$\frac{125 }{100}$$ = 7.5x

the turnover of Patanjali = 3x × $$\frac{ 164 }{100}$$ × $$\frac{ 175 }{100}$$ = 8.61x

the turnover of Accenture = $$\frac{20x }{3}$$ × $$\frac{150 }{100}$$ × $$\frac{160 }{100}$$ = 16x

the turnover of Reliance = $$\frac{25x }{3}$$ × $$\frac{180 }{100}$$ × $$\frac{175 }{100}$$ = 26.25x

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

3. If the total turnover of Patanjali at the end of 2012 was $1 billion then find the total turnover of Patanjali at the end of 2017? (round off two decimal) A.$ 6.21 billion
B. $7.21 billion C.$ 4.58 billion
D. $3.12 billion E.$ 2.24 billion

Explanation:
the total turnover of Patanjali at the end of 2017

= 1 × $$\frac{108 }{100}$$ × $$\frac{112 }{100}$$ × $$\frac{132 }{100}$$ × $$\frac{164 }{100}$$ × $$\frac{175 }{100}$$ = \$ 4.58 billion approximately

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?

A. $$\frac{40}{21}$$ : $$\frac{28}{5}$$ : $$\frac{7}{2}$$ : $$\frac{50}{11}$$
B. $$\frac{40}{21}$$ : $$\frac{27}{5}$$ : $$\frac{5}{2}$$ : $$\frac{50}{11}$$
C. $$\frac{40}{21}$$ : $$\frac{28}{5}$$ : $$\frac{5}{2}$$ : $$\frac{40}{11}$$
D. $$\frac{20}{21}$$ : $$\frac{14}{5}$$ : $$\frac{5}{4}$$ : $$\frac{25}{11}$$
E. None of these

Explanation:
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 = $$\frac{40x }{21}$$

For Reliance, 125% of B = 7x

B = $$\frac{28x }{5}$$

For Airtel, 160% of C = 4x

C = $$\frac{5x }{2}$$

For Accenture, 110% of D = 5x

D = $$\frac{50x }{11}$$

The reqd. ratio = $$\frac{40x }{21}$$ : $$\frac{28x }{5}$$ : $$\frac{5x }{2}$$ : $$\frac{50x }{11}$$

= $$\frac{40 }{21}$$ : $$\frac{28 }{5}$$ : $$\frac{5 }{2}$$ : $$\frac{50 }{11}$$

= $$\frac{20}{21}$$ : $$\frac{14}{5}$$ : $$\frac{5}{4}$$ : $$\frac{25}{11}$$

5. Which of the following shows the approximate percentage increase in the turnover of Accenture during the six years?

A. 450%
B. 500%
C. 600%
D. 550%
E. 300%

Explanation:
Let the turnover of Accenture at the end of 2011 = 1 then the turnover of Accenture at the end of 2017

= 1 × $$\frac{110}{100}$$ × $$\frac{130}{100}$$ × $$\frac{125}{100}$$ × $$\frac{140}{100}$$ × $$\frac{150}{100}$$ × $$\frac{160}{100}$$ = 6.006

Reqd. % = $$\frac{(6 – 1)}{1}$$ × 100 = approximately 500%
