You can put this solution on YOUR website!
f = father's weight
w = wife's weight
d = daughter's weight.

the daughter weights 29 kgs.

since the wife weighs 23 kgs more than the daughter, then the wife weighs 29 + 23 = 52 kgs

since the father weighs 14 kgs more than his wife, then the father weighs 14 + 52 = 66 kgs.

you get:

f = 66
w = 52
d = 29

the sum of their weights is 66 + 52 + 29 = 147 kgs.

the average of their weights is 147 / 3 = 49 kgs.
