Total number of erasers that Linda and Usha shared = 100%
If Linda gave 243 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 Linda gave to Usha
= 77% - 50%
= 27%
27% → 243
1% → 243 ÷ 27 = 9
Number of erasers that Linda had
= 77%
= 77 x 9
= 693
Answer(s): 693
