There were some pomegranates, lemons and kiwis. The number of pomegranates was five times the number of lemons. The total number of pomegranates and lemons was one-quarter of the number of kiwis. There were 150 fruits altogether. All the kiwis were sold at 6 for $14. How much money was collected from the sale of the kiwis?
Number of lemons = 1 u
Number of pomegranates = 5 u

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

Number of kiwis
= 4 x 6 u
= 24 u

Total number of fruits
= 1 u + 5 u + 24 u
= 30 u

30 u = 150

1 u = 150 ÷ 30 = 5

Number of kiwis sold
= 24 u
= 24 x 5
= 120

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

Amount collected from the sale of kiwis
= 20 x 14
= $280

Answer(s): $280
