A sum of rs. 410 was divided among 50 boys and girls. Each boy got rs. 9 and each girl got rs. 6.50. Find the number of girls.
Solution:
Let the number of girls be x.
So, the number of boys will be 50-x.
According to the question, 
9(50-x) + 6.5x = 410
450 - 9x + 6.5x = 410
450 - 2.5x = 410
40 = 2.5x
x = 16
Hence, the number of girls is 16.
