Two trains, Train A and Train B, weigh a total of 192 tons. Train A is heavier than Train B. The difference of their weights is 120 tons. What is the weight of each train?​

For simplicity sake, let's call Train A "A" and Train B "B". 

A + B = 192

 

A > B

 

A - B = 120

 

192 ÷ 2 = 96

 

96 ± 120 ÷ 2 = 96 ± 60 = 156, 36

 

Train A weighs 156 tons and Train B weighs 36 tons :)

B   +        B + 120     = 192

2 B = 72

B = 36 tons      A = 192-36=156 tons
