Monthly savings and expenditure of A initially is Rs. 3200 and Rs. 6800, respectively. Monthly expenditure of A now = 0.65 × 6800 = Rs. 4420 Monthly savings of A now = 1.35 × 3200 = Rs. 4320 Monthly income of A now = 4420 + 4320 = Rs. 8740 Desired percentage decrease = [(10000 – 8740)/10000] × 100 = 12.6%
