60% of the lollipops in Packet E were cheese lollipops and the rest were cherry lollipops. Packet F had 25% more cheese lollipops than Packet E and twice as many lollipops than the total number of lollipops in Packet E. Find the percentage of the cherry lollipops in Packet F that would need to be transferred into Packet E, so that there were an equal number of cheese and cherry lollipops in Packet E.

	Packet E		Packet F
	Cheese	Cherry	Cheese	Cherry
	5 u		10 u
Before	3 u	2 u	3.75 u	6.25 u
Change		+ 1 u		- 1 u
After	3 u	3 u	3.75 u	5.25 u

60% = ⁶⁰₁₀₀ = ³₅
100 %+ 25% = 125%

 Total number of lollipops in Packet E
= 3 u + 2 u
= 5 u

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

Number of cheese lollipops in Packet F
= 125% x 3 u
=  ¹²⁵₁₀₀ x 3 u
= 3.75 u

Number of cheese lollipops in Packet F
= 10 u - 3.75 u
= 6.25 u

Number of cherry lollipops to be transferred from Packet F to Packet E
= 3 u - 2 u
= 1 u

Percentage of lollipops to be transferred from Packet F
= ¹_6.25 x 100%
= 16%

Answer(s): 16%
