The average number of apples in Container Q, Container R and Container S is 27 and it is 6 more than the average number of lemons in the 3 containers. ¹₇ of the lemons are in Container Q and the lemons in Container Q is 30% of the number of lemons in Container R. If each container has the same number of fruits, what percentage of the fruits in Container S are apples?
Average number of lemons
= 27 - 6
= 21

Total number of lemons
= 3 x 21
= 63

Total number of apples
= 3 x 27 
= 81

Total number of fruits
= 63 + 81
= 144

Number of fruits in each container
= 144 ÷ 3
= 48

Lemons in Container Q	Lemons in Container R	Lemons in Container S	Total lemons
1x3	6x3		7x3
3x1	10x1
3 u	10 u	8 u	21 u

30% = ³⁰₁₀₀ = ³₁₀

The number of lemons in Container Q is repeated.  Make the number of lemons in Container Q the same.  LCM of 1 and 3 is 3. 

Total number of lemons
= 3 u + 10 u + 8 u
= 21 u

21 u = 63

1 u = 63 ÷ 21 = 3

Number of lemons in Container S
= 8 u
= 8 x 3
= 24

Number of apples in Container S
= 48 - 24
= 24

Percentage of the fruits in Container S are apples
= ²⁴₄₈ x 100%
= 50%

Answer(s): 50%
