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

1.
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
Answer: Option
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   =>   I1 = 155x ... (i)
x 100 x 100

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

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

    I1 =
( 155x )
100
= 155 => 0.91 => 9 : 10.
I2
( 170x )
100
170 1

Let us 34 is 100%.

Then calculate percentage 31 and I found it 91.

Then we have 91/100 == 9.1/10.

Then question is talking about approximately so we can write it as 9/10.
