Total number of pens that Zoe and Betty shared = 100%
If Zoe gave 95 pens to Betty, 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 Zoe gave to Betty
= 69% - 50%
= 19%
19% → 95
1% → 95 ÷ 19 = 5
Number of pens that Betty had
= 31%
= 31 x 5
= 155
Answer(s): 155
