Total number of erasers that Eva and Rachel shared = 100%
If Eva gave 90 erasers to Rachel, both would have the same number of erasers.
Number of erasers that each would have in the end
= 100% ÷ 2
= 50%
Number of erasers that Eva gave to Rachel
= 65% - 50%
= 15%
15% → 90
1% → 90 ÷ 15 = 6
Number of erasers that Rachel had
= 35%
= 35 x 6
= 210
Answer(s): 210
