Show answer & explanation

Correct answer: D

Let A's income be 3x and B's income be 2x. Let A's expenses be 5y and B's expenses be 3y.

Given savings are Rs. 3000 for both.

  • Equation 1: 3x - 5y = 3000

  • Equation 2: 2x - 3y = 3000

Solving the system of equations:

  • Multiply Eq 1 by 3: 9x - 15y = 9000

  • Multiply Eq 2 by 5: 10x - 15y = 15000

Subtracting gives x = 6000

A's Income = 3x = 3 * 6000 = Rs. 18000.
