Kimberly spent $44 on some starfruits, kiwis and chikoos in the ratio of 4 : 2 : 5. The number of starfruits was ¹₅ the number of kiwis. The ratio of the number of chikoos to the number of kiwis was 5 : 4. The starfruits were sold at 2 for a dollar.

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

Amount spent
Starfruits	Kiwis	Chikoos	Total
4 u	2 u	5 u	11 u

Total amount spent on fruits
= 4 u + 2 u + 5 u
= 11 u

11 u = 44

1 u = 44 ÷ 11 = 4

Amount that Kimberly spent on starfruits
= 4 u
= 4 x 4
= $16 

Total number of starfruits that Kimberly bought
= 16 x 2
= 32

Number of fruits bought
Starfruits	Kiwis	Chikoos
1x4	5x4
	4x5	5x5
4 p	20 p	25 p

The number of kiwis bought is repeated.  Make the number of kiwis the same.  LCM of 4 and 5 is 20.

4 p = 32

1 p = 32 ÷ 4 = 8

Total number of fruits that Kimberly bought
= 4 p + 20 p + 25 p
= 49 p
= 49 x 8
= 392

(b)
Total number of kiwis that Kimberly bought
= 20 p
= 20 x 8
= 160

Total amount that Kimberly paid for the kiwis
= 2 u
= 2 x 4
= $8

Price of each kiwi
= 8 ÷ 160
= $0.05 

Answer(s): (a) 392; (b) $0.05
