Correct Answer - Option 2 : Rs. 4,000
Given:
The incomes of A and B are in the ratio 3 : 2.
The expenditure of A and B are in the ratio 5 : 3.
The saving of each is Rs. 1000
Concept Used:
Income = Expenditure + Saving
Calculation:
Let the income of A and B be 3x and 2x
The expenditure of A = 3x - 1000
The expenditure of B = 2x - 1000
According to the question;
⇒ (3x - 1000)/(2x - 1000) = 5/3
⇒ 9x - 3000 = 10x - 5000
⇒ x = 2000
The income of B = 2 × 2000 = Rs. 4,000
∴ The income of B is Rs. 4,000.
