Question

A man spends 30% of his salary on House rent,
40% on Food, 10% on the Education of children and
the rest he saves. If he saves Rs 1600 per month,
how much is his monthly salary? *​

Answer 1

Answer:

30%+40%+10%=80%

100%-80%=20%

therefore, 20%of x= 1600

20/100×x=1600

x=1600×100/20

x=1600×5

x=8000

so, the monthly salary of man is 8000
