Question 135

Expenditure of Company ‘B’ in 1996 is equal to the income of Company ‘A’ in 1998. What is the respective ratio of the expenditure of Companies B and A in 1996 and 1998 respectively ?

Solution

Let the income of A in 1998 be x

So, expenditure of B in 1996 = x

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

for A in 1998,

.65 = (x-E)/E => x =1.65 E

Ratio of expenditures = x:E = 1.65:1 = 33: 20
