Total number of stamps that Roshel and Olivia shared = 100%
If Roshel gave 91 stamps to Olivia, 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 Roshel gave to Olivia
= 63% - 50%
= 13%
13% → 91
1% → 91 ÷ 13 = 7
Number of stamps that Olivia had
= 37%
= 37 x 7
= 259
Answer(s): 259
