Monthly income of A and B are in the ratio of 4 : 3 and their expenses bear the ratio 3 : 2. Each of them saves ₹ 6,000 at the end of the month, then the monthly income of A is

1. ₹ 12,000
2. ₹ 24,000
3. ₹ 30,000
4. ₹ 60,000

Correct Option: B

Let the monthly income of A and B be ₹ 4x and ₹ 3x respectively and their expenditures be ₹ 3y and Rs. 2y respectively.
∴ 4x – 3y = 6000
and 3x – 2y = 6000
⇒ 4x – 3y = 3x – 2y
⇒ x = y
∴ 4x – 3y = 6000
⇒ x = 6000
⇒ A’s monthly income = 4x
= ₹ 24000
