Let the collection of money done by boys and girls be x and y respectively.

Then, x + y = 25000         ....(i)

And, y = x + 10000

That is, y - x = 10000         ....(ii)

Solving equations (i) and (ii),

2y = 35000 

Hence, y = 17500 and x = 7500

Therefore, the money collected by boys is Rs. 7500 and that by girls is Rs. 17500.
