Percent Profit Earned by a Company Over the Years.

%Profit = (Income - Expenditure)/Expenditure x 100

Rs. 104 crores

Rs. 145 crores

Rs. 160 crores

Rs. 185 crores

View answer & explanation

Correct answer is C

Let the expenditure is 1998 be Rs. x crores.

Then, 65 = ((264 - x)/x) x 100

=> 65/100 = (264/x) - 1

=> x = (264 x100)/165 = 160.

Therefore Expenditure in 1998 = Rs. 160 crores.

The following line graph gives the annual percent profit earned by a Company during the period 1995 - 2000.

Percent Profit Earned by a Company Over the Years.

%Profit = (Income - Expenditure)/Expenditure x 100

If the expenditures in 1996 and 1999 are equal, then the approximate ratio of the income in 1996 and 1999 respectively is?

1:1

2:3

13:14

9:10

View answer & explanation

Correct answer is D

Let the expenditure in 1996 = x.

Also, let the incomes in 1996 and 1999 be I₁ and I₂ respectively.

Then, for the year 1996, we have:

55 = (I₁ - x)/x x 100 => 55/100 = I₁/x - 1 => I₁ = 155x/100 ... (i)

70 = (I₂ - x)/x x 100 => 70/100 = I₂/x - 1 => I₂ = 170x/100 ... (ii)

From (i) and (ii), we get:

I₁/I₂ = (155x/100)/(170x/100) = 155/170 ≈ 0.91/1 ≈ 9 : 10
