70% of the turkish delights in Packet P were cherry turkish delights and the rest were apple turkish delights. Packet Q had 25% more cherry turkish delights than Packet P and four times as many turkish delights than the total number of turkish delights in Packet P. Find the percentage of the apple turkish delights in Packet Q that would need to be transferred into Packet P, so that there were an equal number of cherry and apple turkish delights in Packet P.

	Packet P		Packet Q
	Cherry	Apple	Cherry	Apple
	10 u		40 u
Before	7 u	3 u	8.75 u	31.25 u
Change		+ 4 u		- 4 u
After	7 u	7 u	8.75 u	27.25 u

70% = ⁷⁰₁₀₀ = ⁷₁₀
100 %+ 25% = 125%

 Total number of turkish delights in Packet P
= 7 u + 3 u
= 10 u

Total number of turkish delights in Packet Q
= 4 x 10 u 
= 40 u

Number of cherry turkish delights in Packet Q
= 125% x 7 u
=  ¹²⁵₁₀₀ x 7 u
= 8.75 u

Number of cherry turkish delights in Packet Q
= 40 u - 8.75 u
= 31.25 u

Number of apple turkish delights to be transferred from Packet Q to Packet P
= 7 u - 3 u
= 4 u

Percentage of turkish delights to be transferred from Packet Q
= ⁴_31.25 x 100%
= 12.8%

Answer(s): 12.8%
