The following bar graph shows the Income and Expenditures (in million US $) of five companies in the year 2001. The percent profit or loss of a company is given by: [text{%Profit/Loss} = left(dfrac{text{Income – Expenditure}}{text{Expenditure}}right) × 100]  Q. Common Information Question: 4/5 For Company$R$, if the expenditure had increased by$20%$in year$2001$from year$2000$and the company had earned profit of$10%$in$2000$, what was the Company's income in$2000$(in million US $$)?  ✖ A. 35.75 ✖ B. 37.25 ✖ C. 38.5 ✔ D. 41.25 Solution: Option(D) is correct Let, the expenditure of Company R in 2000 be x million US \$$ Then, expenditure of Company$R$in 2001:$=\left(\dfrac{120}{100}\right) ×x$million US$\$$⇒ \left(\dfrac{120x}{100}\right) = 45 ⇒ x = 37.5 i.e., expenditure of Company R in 2000 = 37.5 million US \$$

Let the income of Company $R$ in $2000$ be $I$ million US \$\$$Then, 10 = \left[\dfrac{I - 37.5}{37.5} × 100\right] [\because % Profit in 2000 = 10%] ⇒ I - 37.5 = 3.75 ⇒ I = 41.25 i.e., Income of Company R in 2000 = 41.25 million US \$$
