Total number of erasers that Shannon and Usha shared = 100%
If Shannon gave 192 erasers to Usha, both would have the same number of erasers.
Number of erasers that each would have in the end
= 100% ÷ 2
= 50%
Number of erasers that Shannon gave to Usha
= 82% - 50%
= 32%
32% → 192
1% → 192 ÷ 32 = 6
Number of erasers that Usha had
= 18%
= 18 x 6
= 108
Answer(s): 108
