Total number of stamps that Cindy and Dana shared = 100%
If Cindy gave 250 stamps to Dana, 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 Cindy gave to Dana
= 75% - 50%
= 25%
25% → 250
1% → 250 ÷ 25 = 10
Number of stamps that Cindy had
= 75%
= 75 x 10
= 750
Answer(s): 750
