b = g + 334

b + g = 572

substituting
... g + 334 + g = 572
Let boys=x & girls=y x-y=334 i.e eqn 1 x+y=572 i.e eqn 2 put x=572-y from eqn 2 in eqn 1 ie (572-y)-y=334 -2y=-572+334 -2y=-238 hence y=119 put y=119 into eqn 1 x-119=334 x=453 Hence boys=453 girls=119
B 453,g 119
Let the no. Of girl be. X
no .of girl =x
no.of boy = x+334
Total no .of strength= 572
A/Q
X+(x+334)=572
2x+334=572
2x=572-334
2x=238
X=238/2
X=119
Very good ans
