Total number of coins that Usha and Tiffany shared = 100%
If Usha gave 48 coins to Tiffany, both would have the same number of coins.
Number of coins that each would have in the end
= 100% ÷ 2
= 50%
Number of coins that Usha gave to Tiffany
= 66% - 50%
= 16%
16% → 48
1% → 48 ÷ 16 = 3
Number of coins that Usha had
= 66%
= 66 x 3
= 198
Answer(s): 198
