1. A dealer buys dry fruits at Rs. 100, Rs. 80, and Rs. 60 per kilogram. He mixes them in the ratio 3:4:5 by weight and sells at a profit of 50%. At what price per kilogram does he sell the dry fruits?
Price of total dry fruits = 3 × 100 + 4 × 80 + 5 × 60 = Rs. 920
SP = 920 + 50% of 920 = 1380
Hence,
Price of mix dry fruits per kg = = Rs. 115
Solution:
Let the dealer buys 3 kg, 4 kg and 5 kg.Price of total dry fruits = 3 × 100 + 4 × 80 + 5 × 60 = Rs. 920
SP = 920 + 50% of 920 = 1380
Hence,
Price of mix dry fruits per kg = = Rs. 115
