1. girls = 2/5 * 25 = 10
boys = 25-10 = 15

If each girl had g books, each boy had g/3 book

total books: 10g + 15g/3 = 135
15g = 135
g = 9

so each girl had 9 books, each boy had 3.

10*9 + 15*3 = 90 + 45 = 135 books in all

2. Girls= 2/5*25= 10
Boys = 3/5*25= 15
All books= 135 books
135÷3= 45÷15= 3*3
= 9 books
