Maths Problem

Hi Sunny,
My daughter, have attended your PR. 6 sesson.
I have one of her Pr. 6 problem that I know the answer but do not know how to present to her. Based on your method, how do you solve the following question:
Ai Tong School organized a 2-day camp. On the first day, the number of boys was 600 more than the girls. On the second day, the number of boys decreased by 10% but the number of girls increased by 10%. If there were 2540 children on the second day, how many children were there on the first day?
Appreciate your enlightening on the solution.
Mr Lee
