The following bar graph shows the Income and Expenditures (in million US $) of five companies in the year 2001. The percent profit or loss of a company is given by: [text{%Profit/Loss} = left(dfrac{text{Income – Expenditure}}{text{Expenditure}}right) × 100]  Q. Common Information Question: 5/5 If the income of Company$Q$in 2001 was$10%$more than its income in$2000$and the Company had earned a profit of$20%$in$2000$, then its expenditure in$2000$(in million US $$) was?  ✖ A. 28.28 ✔ B. 30.3 ✖ C. 32.32 ✖ D. 34.34 Solution: Option(B) is correct Let the income of Company Q in 2001 = x million US \$$ Then, income of Company in$2001$:$= \left(\dfrac{110}{100}\right) × x$million US$\$$⇒ \left(\dfrac{110x}{100}\right)= 40 ⇒ x = \left(\dfrac{400}{11}\right) i.e., income of Company Q in 2000: =\left(\dfrac{400}{11}\right) million US \$$

Let the expenditure of Company $Q$ in $2000$ be $E$ million US \$\$$Then, 20 = \dfrac{[400/11 - E]}{E} × 100 [\because % Profit = 20% ] ⇒ 20 =\left[\dfrac{400}{11E} – 1\right] × 100 ⇒ E = \left(\dfrac{400}{11}\right)× \left(\dfrac{100}{120}\right) = 30.30 ⇒ Expenditure of Company Q in 2000 =30.30 million US \$$
