Problems Involving Two Variables Concept

Dear Sunny,

I have encountered a math's problem for primary 6, could you please advise me how to solve it?

There were a total of 820 boys and girls at a funfair. After 3/4 of the boys and 3/5 of the girls left the funfair, there were 120 more girls than boys remaining behind. How many boys were there at the funfair at first?

Thanks for your help
