Study the following graph carefully and give answers.
Percentage Profit/ Loss = $$\frac{Income- Expenditure}{Expenditure} \times 100$$
If the income of company A increased by 10% in year 2000 from year 1999 and profit earned in 1999 was 20 what was its expenditure in 1999? (The value upto decimal places in crores)
Let the expenditure in 1999 be e
So profit = income - expenditure
20 = Income - e
Income in 2000 is 37.5
So, income in 1999 = 37.5 /1.1 (10% growth from 1999) = 34.09
So, 34.09 - 20 = 14.09
