There were some persimmons, pomegranates and chikoos. The number of persimmons was four times the number of pomegranates. The total number of persimmons and pomegranates was one-third of the number of chikoos. There were 160 fruits altogether. All the chikoos were sold at 4 for $14. How much money was collected from the sale of the chikoos?
Number of pomegranates = 1 u
Number of persimmons = 4 u

Total number of pomegranates and persimmons
= 1 u + 4 u
= 5 u

Number of chikoos
= 3 x 5 u
= 15 u

Total number of fruits
= 1 u + 4 u + 15 u
= 20 u

20 u = 160

1 u = 160 ÷ 20 = 8

Number of chikoos sold
= 15 u
= 15 x 8
= 120

Number of sets of 4 chikoos
= 120 ÷ 4
= 30

Amount collected from the sale of chikoos
= 30 x 14
= $420

Answer(s): $420
