There were some pomegranates, chikoos and apples. The number of pomegranates was two times the number of chikoos. The total number of pomegranates and chikoos was one-quarter of the number of apples. There were 180 fruits altogether. All the apples were sold at 8 for $8. How much money was collected from the sale of the apples?
Number of chikoos = 1 u
Number of pomegranates = 2 u

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

Number of apples
= 4 x 3 u
= 12 u

Total number of fruits
= 1 u + 2 u + 12 u
= 15 u

15 u = 180

1 u = 180 ÷ 15 = 12

Number of apples sold
= 12 u
= 12 x 12
= 144

Number of sets of 8 apples
= 144 ÷ 8
= 18

Amount collected from the sale of apples
= 18 x 8
= $144

Answer(s): $144
