Total number of pens that Nora and Emma shared = 100%
If Nora gave 330 pens to Emma, 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 Nora gave to Emma
= 83% - 50%
= 33%
33% → 330
1% → 330 ÷ 33 = 10
Number of pens that Nora had
= 83%
= 83 x 10
= 830
Answer(s): 830
