Income of Ramesh is Rs. 40,000. He spends 20% on rent,
15% on clothing, 'a%' on food, 25% on others and saves the rest. If his savings is Rs. 8,000, find the value of 'a'.Solution
Savings as percentage of income = (8000 Ć· 40000) Ć 100 = 20%
So, 20 + 15 + a + 25 + 20 = 100
Or, 80 + a = 100
Or, a = 20
