Age problem
Post Body
At present, the sum of the parents’ ages is twice the sum of the children’s ages. Five years ago, the sum of the parent’s ages was 4 times the sum of the children’s ages. Fifteen years hence, the sum of the parents’ ages will be equal to the sum of the children’s ages. How many children are there?
Im having trouble understanding how do you put the no of children into an equation here
