In a school the number of girls is 15 more that that of the boys.
Means G = 15 + B ------ 1

now if 19% of the girls were newly joined and 25% of the boys were newly joined
Total Girls are 1.19G
Total Boys are 1.25B

girls is 9 more than that of the boys.
1.19G = 9 + 1.25B ------ 1
Solving 1 and 2
B= 147
G= 147 + 9 = 156
