Nora spent $28 on some starfruits, chikoos and pomegranates in the ratio of 6 : 3 : 5. The number of starfruits was ³₅ the number of chikoos. The ratio of the number of pomegranates to the number of chikoos was 5 : 1. The starfruits were sold at 3 for a dollar.

1. How many fruits did she buy altogether?
2. How much did each chikoo cost?

Amount spent
Starfruits	Chikoos	Pomegranates	Total
6 u	3 u	5 u	14 u

Total amount spent on fruits
= 6 u + 3 u + 5 u
= 14 u

14 u = 28

1 u = 28 ÷ 14 = 2

Amount that Nora spent on starfruits
= 6 u
= 6 x 2
= $12 

Total number of starfruits that Nora bought
= 12 x 3
= 36

Number of fruits bought
Starfruits	Chikoos	Pomegranates
3x1	5x1
	1x5	5x5
3 p	5 p	25 p

The number of chikoos bought is repeated.  Make the number of chikoos the same.  LCM of 1 and 5 is 5.

3 p = 36

1 p = 36 ÷ 3 = 12

Total number of fruits that Nora bought
= 3 p + 5 p + 25 p
= 33 p
= 33 x 12
= 396

(b)
Total number of chikoos that Nora bought
= 5 p
= 5 x 12
= 60

Total amount that Nora paid for the chikoos
= 3 u
= 3 x 2
= $6

Price of each chikoo
= 6 ÷ 60
= $0.10 

Answer(s): (a) 396; (b) $0.10
