Question

Amit earns ₹ 32000 per month. He spends $\frac{1}{4}$ of his income of food; $\frac{3}{10}$ of the remainder on house rent and $\frac{5}{21}$ of the remainder on the education of children. How much money is still left with him?

Answer 1

Amit's income per month = ₹32,000
Money spent on food = $\frac{1}{4}\mathrm{of}₹32,000=\frac{1}{4}\times ₹32,000=₹8,000$
Remaining amount = ₹32,000 − ₹8,000 = ₹24,000
Money spent on house rent = $\frac{3}{10}\times ₹24,000=\mathrm{Rs}7,200$
Money left = ₹24,000 − ₹7,200 = ₹16,800
Money spent on education of children = $\frac{5}{21}\times ₹16,800=₹4,000$
Amount of money still left with him = ₹16,800 − ₹4,000 = ₹12,800
