B Correct answer
Explanation

Total cost = (60 * 5) + (150 * 6) = 300 + 900 = 1200. Total weight = 60 + 150 = 210 kg. Selling price = 210 * 7 = 1470. Gain = 1470 - 1200 = 270.

AI explanation

The total cost price is (60 times 5) plus (150 times 6), which equals 300 plus 900 for a sum of Rs 1200. The total quantity is 210 kg, so the total selling price at Rs 7 per kg is 210 times 7, equalling Rs 1470. The overall gain is the selling price minus the cost price, resulting in 1470 minus 1200 to yield Rs 270.
