70% of the caramel apples in Packet K were cheese caramel apples and the rest were cherry caramel apples. Packet L had 25% more cheese caramel apples than Packet K and four times as many caramel apples than the total number of caramel apples in Packet K. Find the percentage of the cherry caramel apples in Packet L that would need to be transferred into Packet K, so that there were an equal number of cheese and cherry caramel apples in Packet K.

70% =
70100 =
710 100 %+ 25% = 125%
Total number of caramel apples in Packet K
= 7 u + 3 u
= 10 u
Total number of caramel apples in Packet L
= 4 x 10 u
= 40 u
Number of cheese caramel apples in Packet L
= 125% x 7 u
=
125100 x 7 u
= 8.75 u
Number of cheese caramel apples in Packet L
= 40 u - 8.75 u
= 31.25 u
Number of cherry caramel apples to be transferred from Packet L to Packet K
= 7 u - 3 u
= 4 u
Percentage of caramel apples to be transferred from Packet L
=
431.25 x 100%
= 12.8%
Answer(s): 12.8%
