Question
Out of his income of Rs. 60,000, Arjun spent 25% on
groceries, 25% of the remaining income on rent, and saved the rest. If he would have spent Rs. 200 more on groceries and Rs. 400 more on rent, then how much had he saved?Solution
Amount spent on groceries = 60000 × 0.25 = Rs. 15,000 Remaining income after groceries expense = 60000 - 15000 = Rs. 45,000 Amount spent on rent = 45000 × 0.25 = Rs. 11,250 Increased grocery expense = 15000 + 200 = Rs. 15,200 Increased rent expense = 11250 + 400 = Rs. 11,650 Amount saved = 60000 - (15200 + 11650) = Rs. 33,150
