The following graph gives the percentage of profit earned by two Companies X and Y

Important for :
1
If the expenditures of Company X and Y in 2015 were equal and the total income of the two companies in 2015 was Rs. 348 crores, what was the total profit of the two Companies together in 2015?
» Explain it
D
 %Profit = Income – Expenditure × 100 Expenditure

Let the expenditures of each companies X and Y in 2015 be Rs. x crores.

Income of Company X in 2015 be Rs. z crores.

Income of Company Y in 2015 = Rs. (348 – z) crores.

For company X
 50 = z – x × 100 x

→ z = 1.5x ---------- (1)

For company Y

 40 = 348 – z – x × 100 ----------- (2) x

Solving (1) and (2), we get x = 120 and z = 180

Total expenditure of Companies X and Y in 2015 = 2x = Rs. 240 crores.

Total income of Companies X and Y in 2015 = Rs. 348 crores.

Total profit = Rs. (348 – 240) crores = Rs. 108 crores.

Hence, option (D) is correct.

2
The expenditures of two Companies X and Y in 2017 were in the ratio of 1: 2 respectively. What was the respective ratio of their incomes in 2017?
» Explain it
B
Let the expenditures of company X and Y be x and 2x respectively

Let the income of X be E1

Let the income of Y be E2

For company X

 45 = E1 – x × 100 x

 E1 = 145 x 100

For company Y
 65 = E2 – 2x × 100 2x

 E2 = 165 x 50

 Ratio of incomes = E1 = 145 × 50 =  29 : 66 E2 100 165

Hence, option (B) is correct.

3
What is the percentage change in the profit % of company Y from 2014 to 2017?
» Explain it
B
Profit % of company Y in 2017 = 65%

Change in profit % of company Y = 65 – 60 = 5%

 Required % = 5 × 100 = 8.33% 60

Hence, option (B) is correct.

4
If the expenditure of Company Y in 2014 was Rs. 200 crores, what was its income in 2014?
» Explain it
C
 %Profit = Income – Expenditure × 100 Expenditure

Profit percent of Company Y in 2014 = 60%

Let the income of Company Y in 2014 be Rs. x crores.
 x – 200 × 100 = 60 200
x = 120 + 200 = 320

Income of Company Y in 2014 = Rs. 320 crores.

Hence, option (C) is correct.

5
If the incomes of two companies were equal in 2016, then what was the ratio of expenditure of Company X to that of Company Y in 2016?
» Explain it
D
Let the incomes of each of the two Companies X and Y in 2016 be Rs. x.

And let the expenditures of Companies X and Y in 2016 be E1 and E2 respectively.

Then, for Company X we have:

 40 = x – E1 × 100 E1

 E1 = 100x 140

Also, for Company Y we have:
 35 = x – E2 × 100 E2

 E2 = 100x 135

 E1 = 135 : 140 = 27 : 28 E2

Hence, option (D) is correct.
