The father is 59

Step-by-step explanation:

lets say each of the kids are twelve

30*5=150-36=114=59+55

30*5+ 150 the age of everyone in the family added together

12*3= 36 the age of all the kids

150-36=114 the age of the adults added together

we know the mother is 4 years younger than the father so to state off you can take 114 and divide it by two to get what half of it is then take take numbers that are four apart to find the ages that add up to 114.
