Out of his total income, Mr. Kapur spends 20% on house rent and 70% of the rest on house hold expenses. If he saves Rs. 1800 what is his total income (in Rs.) ?
Answer & Solution
Correct Answer:
Option
D
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
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
