Question

Choose the correct answers from the alternatives given.
The monthly incomes of A and B are in the ratio $4:3$. Each of them saves Rs. 600. If the ratio of their expenditure is $3:2$, then what is the monthly income of A?

• A. $Rs.2400$
• B. $Rs.1800$
• C. $Rs.2000$
• D. $Rs.3600$

Answer 1

The correct option is A $Rs.2400$

Let the income of A and B be 4.r and 3x respectively Income - Savings = Expenditure
According to the question,
$\frac{4x-600}{3x-600}=\frac{3}{2}$

$\to 8x-1200=9x-1800$
$x=600$
Income of A = $4x=4\times 600=2400$
Hence, income of A is$2400.$
