80% of the mini cupcakes in Packet T were banana mini cupcakes and the rest were cherry mini cupcakes. Packet U had 30% more banana mini cupcakes than Packet T and twice as many mini cupcakes than the total number of mini cupcakes in Packet T.

80100 =
45 100 %+ 30% = 130%
Total number of mini cupcakes in Packet T
= 4 u + 1 u
= 5 u
Total number of mini cupcakes in Packet U
= 2 x 5 u
= 10 u
Number of banana mini cupcakes in Packet U
= 130% x 4 u
=
130100 x 4 u
= 5.2 u
Number of banana mini cupcakes in Packet U
= 10 u - 5.2 u
= 4.8 u
Number of cherry mini cupcakes to be transferred from Packet U to Packet T
= 4 u - 1 u
= 3 u
Percentage of mini cupcakes to be transferred from Packet U
=
34.8 x 100%
= 62.5%
Answer(s): 62.5%
