Question
Income of Ravi is Rs. 52,800, out of which he spent 35%
on daily expenses, 5% on phone bills and saves the rest. If his income is increased by 15% and he still saves the same, then what is the increase (in Rs.) in his overall expenses?Solution
ATQ, Total expenses of Ravi = 52,800 * (0.35 + 0.05) = 52,800 * 0.40 = Rs. 21,120 Therefore, savings of Ravi = 52,800 - 21,120 = Rs. 31,680 His increased income = 52,800 * 1.15 = Rs. 60,720 His new expenses = 60,720 - 31,680 = Rs. 29,040 Required increase in his expenses = 29,040 - 21,120 = Rs. 7,920
