Question

The gravity on earth is 3 times the gravity on Mars. Neil and Sally go to mars where Neil weighs twice as much as Sally. If their total weight on Mars is 150 pounds how much do each way on earth?

 

Answer 1

Say, weight of Sally on Mars = x

 

        weight of Neil on Mars =  2x

 

  2x +x = 150

  3x = 150

  x= 50 pounds

 2x = 100 pounds

 

Weight of Sally on earth = 50*3=150pounds

Weight of Neil on earth = 100*3 =300 pounds
