Answer 1

Answer:

Paul's age is 9

mother'age is 36

Sister's age is 3

Step-by-step explanation:

Given,

Paul is x years old

Paul=x

His mother is 4 times his age.

mother=4x

His sister is 6 years younger than him

x-sister=6

sister=x-6

All three ages sum to 48.

x+4x+x-6=48

6x-6=48

6(x-1)=48

x-1=8

x=9   Paul's age

mother'age is 4*9=36

Sister's age is 9-6=3
