Question 132

Expenditure of Company ’B’ in 1998 was Rs. 6.5 lakhs, which was equal to the income of Company ‘C’ in 1996. What was the ratio of income of COmpany ‘B’ in 1998 to the expenditure of Company ‘C’ in 1996 ?

Solution

Expenditure of B in 1998 = 6.5 lakhs

Using the formula % p = 100 * (I-E)/E

we get I = 1.8 E = 1.8 * 6.5 = 11.7

Income of C in 1996 is 6.5 lakhs

Using the formula % p = 100 * (I-E)/E

we get I = 1.8 E => E = 6.5/1.8 = 3.61

So, the required ratio = 11.7:3.61 = 3.24 $$\approx$$ 81:25
