There were some oranges, lemons and pomegranates. The number of oranges was five times the number of lemons. The total number of oranges and lemons was half of the number of pomegranates. There were 180 fruits altogether. All the pomegranates were sold at 8 for $9. How much money was collected from the sale of the pomegranates?
Number of lemons = 1 u
Number of oranges = 5 u

Total number of lemons and oranges
= 1 u + 5 u
= 6 u

Number of pomegranates
= 2 x 6 u
= 12 u

Total number of fruits
= 1 u + 5 u + 12 u
= 18 u

18 u = 180

1 u = 180 ÷ 18 = 10

Number of pomegranates sold
= 12 u
= 12 x 10
= 120

Number of sets of 8 pomegranates
= 120 ÷ 8
= 15

Amount collected from the sale of pomegranates
= 15 x 9
= $135

Answer(s): $135
