Total number of stamps that Kathy and Gem shared = 100%
If Kathy gave 60 stamps to Gem, both would have the same number of stamps.
Number of stamps that each would have in the end
= 100% ÷ 2
= 50%
Number of stamps that Kathy gave to Gem
= 60% - 50%
= 10%
10% → 60
1% → 60 ÷ 10 = 6
Number of stamps that Gem had
= 40%
= 40 x 6
= 240
Answer(s): 240
