Question
The only expenses of Arun are on grocery, rent and fun
expenses. Arun spent Rs. 3,000 on fun, amount spent by him on rent is Rs. 9,000 more than that on fun and amount spent on groceries is 150% of that on rent. If he saved 20% of his total income then, find his total income.Solution
Initially, Arun’s rent expense = 3000 + 9000 = Rs. 12,000 Initially, Arun’s grocery expense = 12000 × (150/100) = Rs. 18,000 Initially, total expenses of Arun = 3000 + 12000 + 18000 = Rs. 33,000 = 80% of his income So, initial income of Arun = 33000 × 100/80 = Rs. 41,250
