There were some mangosteens, pomegranates and chikoos. The number of mangosteens was two times the number of pomegranates. The total number of mangosteens and pomegranates was half of the number of chikoos. There were 153 fruits altogether. All the chikoos were sold at 6 for $12. How much money was collected from the sale of the chikoos?
Number of pomegranates = 1 u
Number of mangosteens = 2 u

Total number of pomegranates and mangosteens
= 1 u + 2 u
= 3 u

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

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

Amount collected from the sale of chikoos
= 17 x 12
= $204

Answer(s): $204
