Income of Anjali is Rs. 28,000, out of which she spent
20% on daily expenses, 10% on phone bills and saves the rest. If her income is increased by 8% and she still saves the same, then what is the increase (in Rs.) in her overall expenses?Solution
ATQ, Total expenses of Anjali = 28,000 * (0.20 + 0.10) = 28,000 * 0.30 = Rs. 8,400 Therefore, savings of Anjali = 28,000 - 8,400 = Rs. 19,600 Her increased income = 28,000 * 1.08 = Rs. 30,240 Her new expenses = 30,240 - 19,600 = Rs. 10,640 Required increase in her expenses = 10,640 - 8,400 = Rs. 2,240
