Question

Ratan spend 70% of his income his income increased by 25% and also his expenditure increased by 25% find the percentage increased in his savings

Answer 1

Answer:

25%

Explanation:

(Assuming the original income of Ratan's to be Rs 100).

70% of rs 100 is spent and he has saved rs 30(100-70).

Now, the income is increased by 25% which increases the original income from rs 100 to rs 125 (rs 100+25%).

An increase in expense by 25% increases the original expense from rs 70 to rs 87.5 (rs70+25%).

Now your new savings is rs 37.5 rs.

% increase in savings is 25% (change in savings÷original savings)×100

Here the change in savings is rs 7.5(37.5-30). Original savings is rs 30.

Answer 2

Answer:

Let his income be Rs.100 Expenditure = Rs. 70

Now Income is increased by 25%

New income = 125 expenditure is increased by 25% =

(70+7×2.5)= 87.5 Rs.

Present Savings = 125 - 87.50 = 37.50

Earlier savings = 100 - 70 = 30

Increase in savings = [{(37.5-30)/30}×100]% = {(7.5/30)×100}%= 25%
