If 7 kg of tea of price ₹ 72 per kg is blended with 33 kg of tea of ₹ 87 per kg and 35 kg of ₹ 85 per kg and the mixture is sold at 15% profit, then what is the selling price of the mixture?
Correct Answer: ₹. 97.37 per kg
Explanation:
CP per kg of the mixture = (w1x1 + w2x2 + w3x3) / (w1 + w2 + w3)
= (7 x 72 + 33 x 87 + 35 x 85)/75
= (504 + 2871 + 2975)/75 = 6350/75 = ₹ 84.66
Profit = 15%
∴ SP per kg = ₹ 84.66 + 15% of ₹ 84.66
= ₹ 97.37
