60% of the mini cupcakes in Packet B were chocolate chip mini cupcakes and the rest were strawberry mini cupcakes. Packet C had 25% more chocolate chip mini cupcakes than Packet B and twice as many mini cupcakes than the total number of mini cupcakes in Packet B. Find the percentage of the strawberry mini cupcakes in Packet C that would need to be transferred into Packet B, so that there were an equal number of chocolate chip and strawberry mini cupcakes in Packet B.

60% =
60100 =
35 100 %+ 25% = 125%
Total number of mini cupcakes in Packet B
= 3 u + 2 u
= 5 u
Total number of mini cupcakes in Packet C
= 2 x 5 u
= 10 u
Number of chocolate chip mini cupcakes in Packet C
= 125% x 3 u
=
125100 x 3 u
= 3.75 u
Number of chocolate chip mini cupcakes in Packet C
= 10 u - 3.75 u
= 6.25 u
Number of strawberry mini cupcakes to be transferred from Packet C to Packet B
= 3 u - 2 u
= 1 u
Percentage of mini cupcakes to be transferred from Packet C
=
16.25 x 100%
= 16%
Answer(s): 16%
