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
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
