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