Question

An employee spends 20% of his income on scooter petrol, 2/5 of the salary on house rent and the balance on food. If he spends Rs.4000 on petrol, then what is the expenditure on house rent?

• A. 8000
• B. 12800
• C. 7200
• D. 3200
• E. None of these

Answer 1

The correct option is A

8000

20% of income = 4000

Income = 4000$\times$$\frac{100}{20}$ = Rs. 20,000

$\frac{2}{5}$th of salary = 40% of total

Expense on rent = 40% of 20,000 = Rs 8000
