After transferring beads, there are now 488 beads in bag C, which is 22% more than the original number of beads in bag C. How many beads were in bag A at the beginning?

Bag A had 400 beads in the beginning.
Bag B had 200 and C had 400 too.
400 x 12% = 48 and 200 x 20% = 40
40 + 48 = 88 which made C 488.
Bag A had twice the beads in B.
400 / 2 = 200
