Percentage of mochi balls after Nick received from Bobby
= 100% + 25%
= 125%
Percentage of Nick's mochi balls that Usha had after receiving from Nick
= 60% x 125%
=
60100 x 125%
= 75%
Percentage of mochi balls that Nick had left after giving to Usha
= 125% - 75%
= 50%
100% = 50
Number of mochi balls that Nick had left
= 50% x 50
=
50100 x 50
= 25
