Question
Income of Deepa is Rs. 60,000. She spends 10% on rent,
25% on clothing, 'a%' on food, 30% on others and saves the rest. If her savings is Rs. 9,000, find the value of 'a'.Solution
Savings as percentage of income = (9000 ÷ 60000) × 100 = 15%
So, 10 + 25 + a + 30 + 15 = 100
Or, 80 + a = 100
Or, a = 20
