The average number of persimmons in Container V, Container W and Container X is 31 and it is 10 more than the average number of starfruits in the 3 containers. ¹₇ of the starfruits are in Container V and the starfruits in Container V is 60% of the number of starfruits in Container W. If each container has the same number of fruits, what percentage of the fruits in Container X are persimmons?
Average number of starfruits
= 31 - 10
= 21

Total number of starfruits
= 3 x 21
= 63

Total number of persimmons
= 3 x 31 
= 93

Total number of fruits
= 63 + 93
= 156

Number of fruits in each container
= 156 ÷ 3
= 52

Starfruits in Container V	Starfruits in Container W	Starfruits in Container X	Total starfruits
1x3	6x3		7x3
3x1	5x1
3 u	5 u	13 u	21 u

60% = ⁶⁰₁₀₀ = ³₅

The number of starfruits in Container V is repeated.  Make the number of starfruits in Container V the same.  LCM of 1 and 3 is 3. 

Total number of starfruits
= 3 u + 5 u + 13 u
= 21 u

21 u = 63

1 u = 63 ÷ 21 = 3

Number of starfruits in Container X
= 13 u
= 13 x 3
= 39

Number of persimmons in Container X
= 52 - 39
= 13

Percentage of the fruits in Container X are persimmons
= ¹³₅₂ x 100%
= 25%

Answer(s): 25%
