You can put this solution on YOUR website! Let their ages be (x)
Girls age =half(x), which x represent her mother
mothers age =x-5
dads age = total age - total sum of the ages of the girl and her mothers age.
therefore, total ages is 100
so, 1/2x + x - 5 + x = 100
x + 2x - 10 + 2x = 200
5x = 190
x = 38
.
. . Girls age is 1/2x
1/2(38) = 19yrs
Mothers age is = x-5
= 38-5
= 33yrs
Dads age is = 100 - (19 + 33)
= 100 - 52
= 47yrs
