Question

Two trains, Train A and Train B, weigh a total of 407 tons. Train A is heavier than Train B. The difference of their weight is 249 tons. What is the weight of each train

Answer 1

A = 328 tons, B = 79 tons.

Explanation:

A + B = 407

A - B = 249

Cancel b out of the equation, then add the rest.

2A = 656, A=328 tons

A + B = 407, B = 407-328

B = 79 tons
