The average number of apples in Container U, Container V and Container W is 30 and it is 10 more than the average number of kiwis in the 3 containers. ¹₅ of the kiwis are in Container U and the kiwis in Container U is 40% of the number of kiwis in Container V. If each container has the same number of fruits, what percentage of the fruits in Container W are apples?
Average number of kiwis
= 30 - 10
= 20

Total number of kiwis
= 3 x 20
= 60

Total number of apples
= 3 x 30 
= 90

Total number of fruits
= 60 + 90
= 150

Number of fruits in each container
= 150 ÷ 3
= 50

Kiwis in Container U	Kiwis in Container V	Kiwis in Container W	Total kiwis
1x2	4x2		5x2
2x1	5x1
2 u	5 u	3 u	10 u

40% = ⁴⁰₁₀₀ = ²₅

The number of kiwis in Container U is repeated.  Make the number of kiwis in Container U the same.  LCM of 1 and 2 is 2. 

Total number of kiwis
= 2 u + 5 u + 3 u
= 10 u

10 u = 60

1 u = 60 ÷ 10 = 6

Number of kiwis in Container W
= 3 u
= 3 x 6
= 18

Number of apples in Container W
= 50 - 18
= 32

Percentage of the fruits in Container W are apples
= ³²₅₀ x 100%
= 64%

Answer(s): 64%
