The average number of lemons in Container C, Container D and Container E is 52 and it is 4 more than the average number of kiwis in the 3 containers. ¹₉ of the kiwis are in Container C and the kiwis in Container C is 40% of the number of kiwis in Container D. If each container has the same number of fruits, what percentage of the fruits in Container E are lemons?
Average number of kiwis
= 52 - 4
= 48

Total number of kiwis
= 3 x 48
= 144

Total number of lemons
= 3 x 52 
= 156

Total number of fruits
= 144 + 156
= 300

Number of fruits in each container
= 300 ÷ 3
= 100

Kiwis in Container C	Kiwis in Container D	Kiwis in Container E	Total kiwis
1x2	8x2		9x2
2x1	5x1
2 u	5 u	11 u	18 u

40% = ⁴⁰₁₀₀ = ²₅

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

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

18 u = 144

1 u = 144 ÷ 18 = 8

Number of kiwis in Container E
= 11 u
= 11 x 8
= 88

Number of lemons in Container E
= 100 - 88
= 12

Percentage of the fruits in Container E are lemons
= ¹²₁₀₀ x 100%
= 12%

Answer(s): 12%
