Total number of pens that Olivia and Roshel shared = 100%
If Olivia gave 231 pens to Roshel, both would have the same number of pens.
Number of pens that each would have in the end
= 100% ÷ 2
= 50%
Number of pens that Olivia gave to Roshel
= 83% - 50%
= 33%
33% → 231
1% → 231 ÷ 33 = 7
Number of pens that Roshel had
= 17%
= 17 x 7
= 119
Answer(s): 119
