There were some passion fruits, mangosteens and pomegranates. The number of passion fruits was two times the number of mangosteens. The total number of passion fruits and mangosteens was half of the number of pomegranates. There were 153 fruits altogether. All the pomegranates were sold at 6 for $9. How much money was collected from the sale of the pomegranates?
Number of mangosteens = 1 u
Number of passion fruits = 2 u

Total number of mangosteens and passion fruits
= 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 = 153

1 u = 153 ÷ 9 = 17

Number of pomegranates sold
= 6 u
= 6 x 17
= 102

Number of sets of 6 pomegranates
= 102 ÷ 6
= 17

Amount collected from the sale of pomegranates
= 17 x 9
= $153

Answer(s): $153
