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
