Total number of pens that Min and Jaslyn shared = 100%
If Min gave 40 pens to Jaslyn, 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 Min gave to Jaslyn
= 70% - 50%
= 20%
20% → 40
1% → 40 ÷ 20 = 2
Number of pens that Min had
= 70%
= 70 x 2
= 140
Answer(s): 140
