Question
Anil spends 20% of the monthly income on the
reconstruction of his house, 15% on basic needs, 10% of the remaining on travelling. If he spends (100/9)% of the remaining income on food and he saves Rs.7280, then find the monthly income of Anil.Solution
Let monthly income of Anil = Rs. 100x Amount spend on reconstruction and on basic needs = 100x × [(20 + 15)/100] = 35x Amount spend on travelling = (100x – 35x) × (10/100) = 6.5x Amount spend on food = (100x – 35x – 6.5x) × (1/9) = 6.5x According to the question, => 100x – 35x – 6.5x – 6.5x = 7280 => x = 140 Therefore, his monthly income = 100 × 140 = Rs.14000
