Question
Two blends of a commodity costing Rs. 70 and Rs. 80 per
kg respectively are mixed in the ratio of 2:3 by weight. If one-fifth of the mixture is sold at Rs. 92 per kg and the remaining at the rate of Rs. 110 per kg, then find the Profit percent?Solution
Ratio = 2 : 3 Let the first blend be 2 kg and second blend be 3 kg. Total Cost Price = (70 × 2) + (80 × 3) = 140 + 240 = Rs. 380 Total SP = (1 × 92) + (4 × 110) = Rs. 532 Profit = 532 – 380 = 152 Required Profit% = (152/380) × 100 = 40%
