80% of the lollipops in Packet K were apple lollipops and the rest were cheese lollipops. Packet L had 30% more apple lollipops than Packet K and twice as many lollipops than the total number of lollipops in Packet K. Find the percentage of the cheese lollipops in Packet L that would need to be transferred into Packet K, so that there were an equal number of apple and cheese lollipops in Packet K.

	Packet K		Packet L
	Apple	Cheese	Apple	Cheese
	5 u		10 u
Before	4 u	1 u	5.2 u	4.8 u
Change		+ 3 u		- 3 u
After	4 u	4 u	5.2 u	1.8 u

80% = ⁸⁰₁₀₀ = ⁴₅
100 %+ 30% = 130%

 Total number of lollipops in Packet K
= 4 u + 1 u
= 5 u

Total number of lollipops in Packet L
= 2 x 5 u 
= 10 u

Number of apple lollipops in Packet L
= 130% x 4 u
=  ¹³⁰₁₀₀ x 4 u
= 5.2 u

Number of apple lollipops in Packet L
= 10 u - 5.2 u
= 4.8 u

Number of cheese lollipops to be transferred from Packet L to Packet K
= 4 u - 1 u
= 3 u

Percentage of lollipops to be transferred from Packet L
= ³_4.8 x 100%
= 62.5%

Answer(s): 62.5%
