**Steve**, Wednesday, March 7, 2012 at 12:39pminitially, b/g = 1/4

after some left, (b-2)/(g-48) = 2/7 since there were groups of 2 boys and 7 girls.

g=4b

7(b-2) = 2(4b-48)

b = 82

so g = 328

so, at first there were 410 children

after kids left, there were

80 boys

280 girls

making 40 groups of 2boys and 7girls
