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

	Packet X		Packet Y
	Apple	Apricot	Apple	Apricot
	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 X
= 7 u + 3 u
= 10 u

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

Number of apple turkish delights in Packet Y
= 125% x 7 u
=  ¹²⁵₁₀₀ x 7 u
= 8.75 u

Number of apple turkish delights in Packet Y
= 40 u - 8.75 u
= 31.25 u

Number of apricot turkish delights to be transferred from Packet Y to Packet X
= 7 u - 3 u
= 4 u

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

Answer(s): 12.8%
