Wilson invited 90 more boys than girls to his party. Only 3/5 of the boys and 4/7 of the girls turned up at his party. He found that 25 more boys than girls did not come to his party. How many children did he invite to his party?

B==Boys,      G==Girls,    


B  -  G ==90...................(1)
2/5B - 3/7G==25............(2), solve for B, G


B ==475
G==385


B  +  G ==475  +  385 ==860 children were invited.
