There were some oranges, kiwis and pomegranates. The number of oranges was four times the number of kiwis. The total number of oranges and kiwis was one-third of the number of pomegranates. There were 160 fruits altogether. All the pomegranates were sold at 6 for $9. How much money was collected from the sale of the pomegranates?
Number of kiwis = 1 u
Number of oranges = 4 u

Total number of kiwis and oranges
= 1 u + 4 u
= 5 u

Number of pomegranates
= 3 x 5 u
= 15 u

Total number of fruits
= 1 u + 4 u + 15 u
= 20 u

20 u = 160

1 u = 160 ÷ 20 = 8

Number of pomegranates sold
= 15 u
= 15 x 8
= 120

Number of sets of 6 pomegranates
= 120 ÷ 6
= 20

Amount collected from the sale of pomegranates
= 20 x 9
= $180

Answer(s): $180
