Total number of cards that Anna and Min shared = 100%
If Anna gave 210 cards to Min, both would have the same number of cards.
Number of cards that each would have in the end
= 100% ÷ 2
= 50%
Number of cards that Anna gave to Min
= 71% - 50%
= 21%
21% → 210
1% → 210 ÷ 21 = 10
Number of cards that Min had
= 29%
= 29 x 10
= 290
Answer(s): 290
