Question 57
The bar chart given below shows the ratio of expenditure to revenue for seven consecutive years Y1, Y2, Y3, Y4, Y5, Y6 and Y7.
Revenue for year Y4 is ₹ 22500. What is the profit for year Y4?
Solution
Ratio of Expenditure to Revenue = 0.9 = 9 : 10
Let expenditure be Rs.9x and Revenue be Rs.10x
Given 10x = 22500 => x = 2250
Then, Profit = Revenue - Expenditure = Rs.10x - Rs.9x = Rs.x = Rs.2250
