Question

Two​ trains, Train A and Train​ B, weigh a total of 351 tons. Train A is heavier than Train B. The difference of their weights is 181 tons. What is the weight of each​ train?

Answer 1

Train A is 266 and Train B is 85

Explanation:

If the difference is 181 tons, then subtract the difference to get double the weight of the lightest train.

351 - 181 = 170

170 ÷ 2 = 85

If B is the lightest, B is 85.

For A, either add the difference back or subtract 85 from 351.

85 + 181 = 351 - 85 = 266
