Let the cost of mangoes per piece be 3x. The cost of bananas per piece be 2x. The cost of guavas per piece be x. According to the question; 6(3x) + 3(2x) + 10(x) = 136 18x + 6x + 10x = 136 34x = 136 x = 4 The cost of mangoes, bananas, and guava is 12, 8, and 4 respectively. Therfore, the cost of 1 mango = 12 Cost of 2 bananas = 8(2) = 16 Cost of 3 guavas = 3(4) = 12 Total cost = 12 + 16 + 12 = 40 |
