Question

Hi, please help to solve this question. Thanks. 

Answer

Let Box A contain 12 units.

Then Box C contains 2 units.

Box B contains 3 units + 4.

Box B contains $10 more than Box C, so 3u + 4 = 2u + 10

1u = 6

Total in the 3 boxes = 12u + 3u + 4 + 2u = 17u + 4 = 17  × 6 + 4 = 102 + 4 = 106

The total amount is $106.

Box A has 6 times as much as C. But 6 is not divisible by 4 so we use 12 units. 

Then C is 1/6 of 12 units = 2 units.
