Total number of cards that Sarah and Kylie shared = 100%
If Sarah gave 150 cards to Kylie, 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 Sarah gave to Kylie
= 80% - 50%
= 30%
30% → 150
1% → 150 ÷ 30 = 5
Number of cards that Kylie had
= 20%
= 20 x 5
= 100
Answer(s): 100
