Finding mass of eight 16 year old boys. When four 12 year old boys has their mass of 144kg
we are going to make some assumptionms here.
1st assumption: all 12 year old boys have the same weight.
2nd assumption: all 16 year old boys have the same weight.
3rd assumption: weight increases from 12 to 16 years at a constant rate.
we have 4 boys weighing 144 kg,
Therefore each 12 year old boy weighs 36 kg
Using our 3rd assumption, at age 16, the child's weight would be 36 *(16/12) = 48 kg
Therefore weight of 8 16 year old boys would be: 8*48 = 384 kg
