    D ₹46 Correct Answer Incorrect Answer

    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
