The average number of mangoes in Box T, Box U and Box V is 32 and it is 4 more than the average number of pomegranates in the 3 boxes. ¹₇ of the pomegranates are in Box T and the pomegranates in Box T is 80% of the number of pomegranates in Box U. If each box has the same number of fruits, what percentage of the fruits in Box V are mangoes?
Average number of pomegranates
= 32 - 4
= 28

Total number of pomegranates
= 3 x 28
= 84

Total number of mangoes
= 3 x 32 
= 96

Total number of fruits
= 84 + 96
= 180

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

Pomegranates in Box T	Pomegranates in Box U	Pomegranates in Box V	Total pomegranates
1x4	6x4		7x4
4x1	5x1
4 u	5 u	19 u	28 u

80% = ⁸⁰₁₀₀ = ⁴₅

The number of pomegranates in Box T is repeated.  Make the number of pomegranates in Box T the same.  LCM of 1 and 4 is 4. 

Total number of pomegranates
= 4 u + 5 u + 19 u
= 28 u

28 u = 84

1 u = 84 ÷ 28 = 3

Number of pomegranates in Box V
= 19 u
= 19 x 3
= 57

Number of mangoes in Box V
= 60 - 57
= 3

Percentage of the fruits in Box V are mangoes
= ³₆₀ x 100%
= 5%

Answer(s): 5%
