There are 14 girls, 11 boys, and their parents at a park. If they split into 3 equally sized playgroups, each group contains 25 people. How many parents were at the park?
There are 3 groups * 25 people/group = <<3*25=75>>75 people in total.
There are 14 girls + 11 boys = <<14+11=25>>25 children in total.
There are 75 people - 25 children = <<75-25=50>>50 parents.
