Answer:
25 girls
Step-by-step explanation:
The method I use is quite odd, but it works.
1. Find the halves of the total and difference: 41/2 = 20.5, 9/2 = 4.5
2. Add and subtract the half of the difference to the half of the total: 20.5 + 4.5 = 25, 20.5 - 4.5 = 16
3. Since there are more girls, the larger number will be the # of girls: 25.
