Question

Take weights of 5 of your friends and find out what there weights will be on the moon and on the mars

Answer 1

Let weight of five friends on earth .... Be.
A=50kg B=30kg C=20kg D=60kg E=120kg.. (an assumption)

So as we know that the weight on moon is 1/6th of the weight on earth.... 

Wm=1/6We 

[we is the weight on earth. And wm is the wieght on moon. ] 
So weight of friends on moon will be...
A=1/6*50=8.3kg
B=1/6*30=5kg
C=1/6*20=3.3kg
D=1/6*60=10kg
E=1/6*120=20kg

Now, weight of friends on mars will be
A= 1/3*50 = 16.6 Kg
B= 1/3*30 10 Kg
C=1/3*20 =6.6 Kg
D= 1/3*60= 20 Kg
E =1/3*120 = 40 Kg
