70% of the lollipops in Packet L were chocolate chip lollipops and the rest were cheese lollipops. Packet M had 25% more chocolate chip lollipops than Packet L and four times as many lollipops than the total number of lollipops in Packet L. Find the percentage of the cheese lollipops in Packet M that would need to be transferred into Packet L, so that there were an equal number of chocolate chip and cheese lollipops in Packet L.

	Packet L		Packet M
	Chocolate Chip	Cheese	Chocolate Chip	Cheese
	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 lollipops in Packet L
= 7 u + 3 u
= 10 u

Total number of lollipops in Packet M
= 4 x 10 u 
= 40 u

Number of chocolate chip lollipops in Packet M
= 125% x 7 u
=  ¹²⁵₁₀₀ x 7 u
= 8.75 u

Number of chocolate chip lollipops in Packet M
= 40 u - 8.75 u
= 31.25 u

Number of cheese lollipops to be transferred from Packet M to Packet L
= 7 u - 3 u
= 4 u

Percentage of lollipops to be transferred from Packet M
= ⁴_31.25 x 100%
= 12.8%

Answer(s): 12.8%
