The average number of mangoes in Container U, Container V and Container W is 56 and it is 2 more than the average number of oranges in the 3 containers. ¹₉ of the oranges are in Container U and the oranges in Container U is 40% of the number of oranges in Container V. If each container has the same number of fruits, what percentage of the fruits in Container W are mangoes?
Average number of oranges
= 56 - 2
= 54

Total number of oranges
= 3 x 54
= 162

Total number of mangoes
= 3 x 56 
= 168

Total number of fruits
= 162 + 168
= 330

Number of fruits in each container
= 330 ÷ 3
= 110

Oranges in Container U	Oranges in Container V	Oranges in Container W	Total oranges
1x2	8x2		9x2
2x1	5x1
2 u	5 u	11 u	18 u

40% = ⁴⁰₁₀₀ = ²₅

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

Total number of oranges
= 2 u + 5 u + 11 u
= 18 u

18 u = 162

1 u = 162 ÷ 18 = 9

Number of oranges in Container W
= 11 u
= 11 x 9
= 99

Number of mangoes in Container W
= 110 - 99
= 11

Percentage of the fruits in Container W are mangoes
= ¹¹₁₁₀ x 100%
= 10%

Answer(s): 10%
