Question

A spends 75% of his income,his income is increased by 20% and he increase his expenditure by 10%.his savings are increased by

Answer 1

Let man's original income be Rs. 100

So in this case
Expenditure >>>>>>> Rs. 75
Savings >>>>>>>>> Rs. 25

Now His new salary = 120/100 × 100
= Rs. 120

In this case expenditure = Rs. 75 + 10% of 75

New Expenditure = Rs. 75 + 7.5
= Rs. 82.5

Therefore,
Savings = 120 - 82.5
= Rs. 37.5

INCREASE IN SAVINGS = 37.5 - 25
= Rs. 12.5

INCREASE % = 12.5/100 × 100
=> 12.5%

ANSWER = 12.5 %
