Victoria has 25% as many stickers as Min. Min has 130% as many stickers as Cathy. If Min gives 60 stickers to Cathy, both will then have an equal number of stickers. Find the average number of stickers the three of them have.

Victoria	Min	Cathy
1x13	4x13
	13x4	10x4
13 u	52 u	40 u

25% = ²⁵₁₀₀ = ¹₄
130% = ¹³⁰₁₀₀= ¹³₁₀

The number of stickers that Victoria has is repeated.  Make the number of stickers that Victoria has the same. LCM of 4 and 13 is 52.

	Min	Cathy	Total
Before	52 u	40 u	92 u
Change	- 6 u	+ 6 u
After	46 u	46 u	92 u

Total number of stickers that Min and Cathy have
= 52 u + 40 u
= 92 u

After Min gives to Cathy, both of them will have the same number of stickers. 

The total number of stickers that Min and Cathy have remains unchanged.

Number of stickers that each of them will have
= 92 u ÷ 2
= 46 u

Number of stickers that Min gives to Cathy
= 52 u - 46 u
= 6 u

6 u = 60

1 u = 60 ÷ 6 = 10

Total number of stickers that three of them have
= 92 u + 13 u
= 105 u

Average number of stickers that each of them have
= 105 u ÷ 3
= 35 u
= 35 x 10
= 350

Answer(s): 350
