Question
Income of Neha is Rs. 39,000, out of which she spent 40%
on daily expenses, 5% on phone bills and saves the rest. If her income is increased by 20% and she still saves the same, then what is the increase (in Rs.) in her overall expenses?Solution
ATQ,\ Total expenses of Neha = 39,000 * (0.40 + 0.05) = 39,000 * 0.45 = Rs. 17,550 Therefore, savings of Neha = 39,000 - 17,550 = Rs. 21,450 Her increased income = 39,000 * 1.20 = Rs. 46,800 Her new expenses = 46,800 - 21,450 = Rs. 25,350 Required increase in her expenses = 25,350 - 17,550 = Rs. 7,800
