2x/5 = # girls in club.

3/4(2x/5) = 6x/20 = 3x/10 = # of girls

not taking part.

B/6 = 12

B = 72 = # of boys in club.

2x/5 + 72 = X pupils.

2x + 360 = 5x

3x = 360

X = 120 pupils, total.

3x/10 = (3*120)/10 = 36 = Girls not

taking part.

a. (B+G)/X=((12+36)/120)*100%=40%.

b. 3x/10 = 360/10 = 36. Girls.
