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	x 100
	Expenditure

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

Answer: Option D

Explanation:

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 100		55	=	I₁	- 1
	x			100		x

I_{1 = 155x / 100 -------- (i)}

70 =	I₂ - x	x 100		70	=	I₂	- 1
	x			100		x

I_{2 = 170X / 100 ----- (ii)}

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

	155x
	100

155

0.91

9 : 10.

	170x
	100
