The average number of pears in Box L, Box M and Box N is 32 and it is 4 more than the average number of apples in the 3 boxes. ¹₇ of the apples are in Box L and the apples in Box L is 40% of the number of apples in Box M. If each box has the same number of fruits, what percentage of the fruits in Box N are pears?
Average number of apples
= 32 - 4
= 28

Total number of apples
= 3 x 28
= 84

Total number of pears
= 3 x 32 
= 96

Total number of fruits
= 84 + 96
= 180

Number of fruits in each box
= 180 ÷ 3
= 60

Apples in Box L	Apples in Box M	Apples in Box N	Total apples
1x2	6x2		7x2
2x1	5x1
2 u	5 u	7 u	14 u

40% = ⁴⁰₁₀₀ = ²₅

The number of apples in Box L is repeated.  Make the number of apples in Box L the same.  LCM of 1 and 2 is 2. 

Total number of apples
= 2 u + 5 u + 7 u
= 14 u

14 u = 84

1 u = 84 ÷ 14 = 6

Number of apples in Box N
= 7 u
= 7 x 6
= 42

Number of pears in Box N
= 60 - 42
= 18

Percentage of the fruits in Box N are pears
= ¹⁸₆₀ x 100%
= 30%

Answer(s): 30%
