Total number of pens that Roshel and Gem shared = 100%
If Roshel gave 77 pens to Gem, 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 Roshel gave to Gem
= 61% - 50%
= 11%
11% → 77
1% → 77 ÷ 11 = 7
Number of pens that Gem had
= 39%
= 39 x 7
= 273
Answer(s): 273
