Question

a man spends 40% of his salary on house rent 20% of the remaining on food 33 1/3% of the remaining on children???s education. he divides the rest into two equal halves and spends one half on entertainments and saves the other half. in a month on which his saving was rs.100

Answer 1

House rent = 40/100

Remaining = 1 - 40/100 = 60/100

Food = 20/100 × 60/100 = 1/5 × 3/5 = 3/25

Remaining = 3/5 - 3/25 = 12/25

Children's education = 100/300 × 12/25 = 4/25

Remaining = 12/25 - 4/25 = 8/25

Savings = 8/25 ÷ 2 = 4/25

4/25 = 100

Income will be :

25/4 × 100 = 625

Rs 625
