Ajay bought 15 kg of dal at the rate of Rs 14.50 per kg and 10 kg at the rate of Rs 13 per kg. He mixed the two and sold the mixture at the rate of Rs 15 per kg. What was his total gain in this transaction ?
A) Rs 1.10
B) Rs 11
C) Rs 16.50
D) Rs 27.50
Answer: D) Rs 27.50
Cost price of 25 kg = Rs. (15 x 14.50 + 10 x 13) = Rs. 347.50. Sell price of 25 kg = Rs. (25 x 15) = Rs. 375. profit = Rs. (375 — 347.50) = Rs. 27.50.
