Total number of buttons that Usha and Gem shared = 100%
If Usha gave 78 buttons to Gem, both would have the same number of buttons.
Number of buttons that each would have in the end
= 100% ÷ 2
= 50%
Number of buttons that Usha gave to Gem
= 63% - 50%
= 13%
13% → 78
1% → 78 ÷ 13 = 6
Number of buttons that Gem had
= 37%
= 37 x 6
= 222
Answer(s): 222
