80% of the turkish delights in Packet R were blueberry turkish delights and the rest were vanilla turkish delights. Packet S had 30% more blueberry turkish delights than Packet R and twice as many turkish delights than the total number of turkish delights in Packet R. Find the percentage of the vanilla turkish delights in Packet S that would need to be transferred into Packet R, so that there were an equal number of blueberry and vanilla turkish delights in Packet R.

	Packet R		Packet S
	Blueberry	Vanilla	Blueberry	Vanilla
	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 turkish delights in Packet R
= 4 u + 1 u
= 5 u

Total number of turkish delights in Packet S
= 2 x 5 u 
= 10 u

Number of blueberry turkish delights in Packet S
= 130% x 4 u
=  ¹³⁰₁₀₀ x 4 u
= 5.2 u

Number of blueberry turkish delights in Packet S
= 10 u - 5.2 u
= 4.8 u

Number of vanilla turkish delights to be transferred from Packet S to Packet R
= 4 u - 1 u
= 3 u

Percentage of turkish delights to be transferred from Packet S
= ³_4.8 x 100%
= 62.5%

Answer(s): 62.5%
