Hi,
Let the mother's age be "x"
Then,
Father's age =x+30
Also,
Child's age =x/2
But the sum of their age is 105
Then,
x+x+30+(x/2)=105
2x+(x/2)=105-30
2x+(x/2)=75.
multiply althrough by 2
4x+x=150
5x=150
x=150/5
x=30
The mother's age is 30yrs
Father's age=x+30
=30+30
=60yrs
Also,Child's age =x/2
=30/2
=15yrs
The mother's age =30yrs
Father's age=60yrs
Child's age=15yrs.
HOPE THIS HELPS,....
Best regards
