Study the following graph to answer the given questions.
Per cent pro t earned by two companies over the given years.
%$$profit=\frac{Income - Expenditure}{Expenditure}\times100$$
Solution
Income of company A in 2002 = Rs. 600 crores
Profit % of company A in 2002 = 60 %
Let expenditure of company A in 2002 = Rs. $$x$$
=> $$\frac{600 - x}{x} \times 100 = 60$$
=> $$\frac{600 - x}{x} = \frac{60}{100} = \frac{3}{5}$$
=> $$5 \times (600 - x) = 3 \times x$$
=> $$3000 - 5x = 3x$$
=> $$5x + 3x = 8x = 3000$$
=> $$x = \frac{3000}{8} = Rs. 375$$ crores
