The difference between the number of boys and girls in a tree planting event is 400. If there are 600 boys at the event, and the number of girls is more than the number of boys, what's 60% of the total number of boys and girls at the event?
If there are 600 boys at the event, and the difference between boys and girls is 400, there are 600+400=1000 girls.
The total number of boys and girls at the event is 1000+600=1600
60% of the total number of boys and girls at the event is 60/100*1600=960
