A. Rs. 7800

B. Rs. 7000

C. Rs. 8000

D. Rs. 7500

Answer: Option D

Solution(By Examveda Team)

Let Mr.kapur income is 100x
House rent 20%, i.e. 20x
Remaining income 100x - 20x = 80x
Now 70% of his remaining income spend in house hold expenses
i.e. 70% of 80x = 56x
Remain saving is 80x - 56x = 24x
According to question
24x = 1800
x = $$\frac{{1800}}{{24}} = 75$$
Mr.kapur income = 100 × 75 = 7500
