There were some kiwis, oranges and pomegranates. The number of kiwis was two times the number of oranges. The total number of kiwis and oranges was half of the number of pomegranates. There were 162 fruits altogether. All the pomegranates were sold at 6 for $6. How much money was collected from the sale of the pomegranates?
Number of oranges = 1 u
Number of kiwis = 2 u

Total number of oranges and kiwis
= 1 u + 2 u
= 3 u

Number of pomegranates
= 2 x 3 u
= 6 u

Total number of fruits
= 1 u + 2 u + 6 u
= 9 u

9 u = 162

1 u = 162 ÷ 9 = 18

Number of pomegranates sold
= 6 u
= 6 x 18
= 108

Number of sets of 6 pomegranates
= 108 ÷ 6
= 18

Amount collected from the sale of pomegranates
= 18 x 6
= $108

Answer(s): $108
