Answer:
There are a number of ways to work the math on this.
60% = 60/100 = 3/5
3/5 * 25 or (3 * 25)/5 =
75/5 = 15
So the exact number is 15 boys, but the way the question is worded, it could be a trick question. It says 60% are boys, but does not specify that the other 40% are all not boys. In that case the answer would be:
15 <= number of boys <= 25
