Question

Out of his salary rohan spends 1\5on rent, 1\3 on food and 1\6 on cloths. What fraction of his salary does he save?

Answer 1

Taking the denominators' LCM,

Rent= 6/30 of salary

Food= 10/30 of salary

Clothes= 5/30 of salary

Adding them up and subtracting from 30/30,

(30-22)/30= 8/30= 2/15 of his salary he saves.
