Question

The average weight of 5 men is increased by 3 kg when one of them who weighs 120 kg is replaced by another man. What is the weight of the new man?

Answer 1

Answer:

Step-by-step explanation:

a+b+c+d+e/5=x

a+b+c+d+e=5x

a+b+c+d=5x-120

a+b+c+d+f/5=X+3

a+b+c+d+f=5x+15

5x-120+f=5x+15

f=135kg

So the weight of the new man is 135kg

Answer 2

Answer:

Step-by-step explanation:

Weight of a new person=120

Total weight of 5men is increased by 3kg ---> 5*3

Weight of a new person=120+(5*3)

Weight of a new person=135
