Total number of stamps that Nora and Usha shared = 100%
If Nora gave 66 stamps to Usha, both would have the same number of stamps.
Number of stamps that each would have in the end
= 100% ÷ 2
= 50%
Number of stamps that Nora gave to Usha
= 83% - 50%
= 33%
33% → 66
1% → 66 ÷ 33 = 2
Number of stamps that Nora had
= 83%
= 83 x 2
= 166
Answer(s): 166
