Answer 1

Answer:

hope it help full for you

Step-by-step explanation:

Consider the five people are a, b, c, d, e and let their average be x.

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

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

Let the person weighing 50kg be a

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

b+c+d+e=5x-50

Let the new person be f

(b+c+d+e+f)/5=x-2

b+c+d+e+f=5x-10

5x-50+f=5x-10

f=50–10=40kg
