A class of 27 pupils was divided equally into 3 groups, A,B and C. A box of marbles was shared among the pupils so that group A had twice the number of marbles Group B had. Each pupil in Group B had 4 marbles more than each pupil in Group C. If the pupils in Group C received a total of 549 marbles, how many marbles were shared out?

b has 9 pupils--27/3=9
c has 9 pupils
each pupil in c has--549/9=61 marbles.
in b every pupil has 65 marbles.
group b has total of 585 marbles(65*9)
group a has total of 585*2=1170marbles
now,1170+585+549=total no. of marbles!!!!(i.e.2304)

27 / 3= 9 (pupils per group)
4 x 9 = 36
549 + 36 = 585 (marbles in group B)
585 x 2 = 1170 (marbles in group A)
1170 + 585 + 549 = 2304 marbles in all.

Group C: 549 marbles
Group B: 549 + (4x9) = 585 marbles
Group A: 585 x 2 = 1170 marbles
1170+585+549 = whatever that equals

I didn't expect that British kids were lazy and disinterested enough to ask for others to do their homework for them; this is the kind of crap I'd expect from Americans.
Do your own work, kid.
