Total number of stamps that Xuan and Marion shared = 100%
If Xuan gave 186 stamps to Marion, 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 Xuan gave to Marion
= 81% - 50%
= 31%
31% → 186
1% → 186 ÷ 31 = 6
Number of stamps that Marion had
= 19%
= 19 x 6
= 114
Answer(s): 114
