In a particular month, a man earns Rs. 7,200. Out of this income, he spends `3/10` on food, `1/4` on house rent, `1/10` on insurance, and `2/25` on holidays. How much did he save in that month?
उत्तर
Earning of a man in a particular month = Rs. 7200
Amount spent on food = `3/10` of Rs. 7200
= Rs. 2160
Amount spent on house rent
= `1/4` of Rs. 7200
= Rs. 1800
Amount spent on insurance
= `1/10` of Rs. 7200
= Rs. 720
Amount spent on holidays
= `2/25` of Rs. 7200
= Rs. 2 × 288
= Rs. 576
∴ Total amount spent = Rs. (2160 + 1800 + 720 + 576) = Rs. 5256
∴ Amount saved = Rs. 7200 − Rs. 5256 = Rs. 1944
