Question
Kiran spent 12% of his monthly income on education, 28%
on entertainment, 15% on rent, 30% on travelling and the rest on savings. If the difference between the amount spent on travelling and the amount spent on savings is Rs. 5400, then find the amount spent on entertainment.Solution
ATQ, Let monthly income of Kiran be Rs. βxβ Amount spent on education = Rs. 0.12x Amount spent on entertainment = Rs. 0.28x Amount spent on rent = Rs. 0.15x Amount spent on travelling = Rs. 0.30x Amount spent on savings = x β (0.12x + 0.28x + 0.15x + 0.30x) = Rs. 0.15x According to the question, 0.30x β 0.15x = 5400 0.15x = 5400 x = Rs. 36,000 Amount spent on entertainment = 28% of 36,000 = Rs. 10,080
