Question
Income of Ankit is Rs. 36,000. He spends 18% on rent,
22% on clothing, 'a%' on food, 28% on others and saves the rest. If his savings is Rs. 5,400, find the value of 'a'.Solution
Savings as percentage of income = (5400 ÷ 36000) × 100 = 15%
So, 18 + 22 + a + 28 + 15 = 100
Or, 83 + a = 100
Or, a = 17
