E. Rs. 4500
Answer: Option C
Solution(By Examveda Team)
Let income of A and B be 3x and 2x respectively. Also, their expenditure is 5y and 3y. Now, according to question, 3x - 5y = 1000 ------- (i) × 3 2x - 3y = 1000 ---------- (ii) × 5 9x - 15y - 10x + 15y = 3000 - 5000 Or, -x = -2000 Or, x = 2000 Then, income of A = 3x = 3 × 2000 = Rs. 6000Join The Discussion

3x.
So,the income of A is 5x+1000
ATQ,
5x+1000/3x+1000=3/2

or, x=1000
So, the income of A is 5x+1000=5*1000+1000=Rs.6000 (Ans)
