Question
Divakar spends 30% of his salary on house rent, 20% of
the remaining amount on shopping, 25% of the remaining on education fees, and the rest is divided between transport and insurance in a 2:1 ratio. If his house rent expenditure increases by 20%, resulting in an increase of Rs. 3600 in the amount spent on house rent, what is the amount spent on insurance?Solution
House rent = x x * 120/100 – x = 3600 x = 3600 * 5 x = 18000 Salary = 100/30 * 18000 = 60000 Amount spends on house rent = 18000 Remaining amount = 60000 – 18000 = 42000 Shopping = 42000 * 20/100 = 8400 Remaining = 42000 – 8400 = 33600 Education fee = 33600 * 25/100 = 8400 Remaining amount = 33600 – 8400 = 25200 Insurance amount = 1/3 * 25200 = Rs.8400
