Total number of stamps that Penelope and Yoko shared = 100%
If Penelope gave 68 stamps to Yoko, 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 Penelope gave to Yoko
= 67% - 50%
= 17%
17% → 68
1% → 68 ÷ 17 = 4
Number of stamps that Penelope had
= 67%
= 67 x 4
= 268
Answer(s): 268
