Question
A dealer buys three types of mangoes at Rs. 40, Rs. 30
and Rs. 10 kg respectively. He mixes them in the ratio of 2:3:4 by weight and sells them at a profit of 38%. At what price does he sell the mangoes?Solution
Suppose the dealer purchases 2kg, 3kg and 4kg of mangoes respectively of each type. Then, the price of total mangoes = (2 x 40 )+ (3 x 30 )+ (4 x 10 )= Rs. 210 As the total mangoes weigh 9kg and the dealer makes a profit of 38%, the selling price of the mangoes per kg = (210 x 138)/(100 x 1/9) = Rs. 32.2
