The numbers of boys and girls in a class was in the ratio 2:5. After 5 girls were transferred to another class, half of the remaining students were boys. How many more girls than boys were there in the class at first?

Answer:

15

Explanation:

If there are 10 boys and 25 girls, which is a ratio of 2:5, then when 5 girls are transferred, there are 10 boys and 20 girls, meaning half of them are boys, so the class started out with 15 more girls than boys.
