There were some chikoos, pomegranates and persimmons. The number of chikoos was five times the number of pomegranates. The total number of chikoos and pomegranates was half of the number of persimmons. There were 180 fruits altogether. All the persimmons were sold at 6 for $15. How much money was collected from the sale of the persimmons?
Number of pomegranates = 1 u
Number of chikoos = 5 u

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

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

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

Amount collected from the sale of persimmons
= 20 x 15
= $300

Answer(s): $300
