Question
A person spends 15% of his income on insurance and 25%
of the remaining income on food. If the amount spent on insurance is Rs. 6,000, then find the amount spent on food.Solution
Let the income of the person be Rs. x.
Amount spent on insurance = 0.15x = Rs. 6,000
Total income = 6,000 ÷ 0.15 = Rs. 40,000
Amount spent on food = 0.25 × (0.85x) = 0.2125x = 40,000 × 0.2125 = Rs. 8,500
