There were some chikoos, starfruits and pears. The number of chikoos was three times the number of starfruits. The total number of chikoos and starfruits was one-third of the number of pears. There were 176 fruits altogether. All the pears were sold at 6 for $12. How much money was collected from the sale of the pears?
Number of starfruits = 1 u
Number of chikoos = 3 u

Total number of starfruits and chikoos
= 1 u + 3 u
= 4 u

Number of pears
= 3 x 4 u
= 12 u

Total number of fruits
= 1 u + 3 u + 12 u
= 16 u

16 u = 176

1 u = 176 ÷ 16 = 11

Number of pears sold
= 12 u
= 12 x 11
= 132

Number of sets of 6 pears
= 132 ÷ 6
= 22

Amount collected from the sale of pears
= 22 x 12
= $264

Answer(s): $264
