₹136. If the ratio of the cost (per piece) of mangoes, bananas and guavas is 3 : 2 : 1, what will be the total cost of 1 mango, 2 bananas and 3 guavas?Solution
Let the cost per piece of mangoes be 3x. Let the cost per piece of bananas be 2x. Let the cost per piece of guavas be x. Then, 6(3x) +3(2x) +10(x) = 136 18x + 6x + 10x = 136 34x = 136 x = 4 Then, the cost per piece of mangoes, bananas and guavas is Rs. 12, Rs. 18 and Rs. 4 respectively. Therefore the cost of 1 mango, 2 bananas and 3 guavas = 12 x 1 + 8 x 2 + 4 x 3 = 12 + 16 + 12 = Rs. 40
