Question

A person saves 25/2% of his monthly salary.if he earns Rs.720,how much does he save every month?

Answer 1

amount he earns = ₹720
amount he saves = 25/2 % of 720
= (25/2) / 100 × 720
= { 25/2 × 1/100 } × 720
= 25/200 × 720
= 0.125 × 720
= ₹90

thus,
the amount he saves in a month = ₹90

Answer 2

percentage of salary saved = 25/2%
Frequent earning he saves amount from = Rs 720

Amount he saved => 25/2% /100
=> 25/2 x 1/100
=> 25/200%

Hence amount he saved every month
=> 25/200 x 720
=> 1/8 x 720 ( 25 and 200 got cancelled )
=> 720/8
=> Rs 90

Amount he saved every month was Rs 90
