Total number of marbles that Gem and Usha shared = 100%
If Gem gave 168 marbles to Usha, both would have the same number of marbles.
Number of marbles that each would have in the end
= 100% ÷ 2
= 50%
Number of marbles that Gem gave to Usha
= 78% - 50%
= 28%
28% → 168
1% → 168 ÷ 28 = 6
Number of marbles that Usha had
= 22%
= 22 x 6
= 132
Answer(s): 132
