Jade spent $20 on some mangoes, chikoos and oranges in the ratio of 5 : 4 : 1. The number of mangoes was ¹₂ the number of chikoos. The ratio of the number of oranges to the number of chikoos was 6 : 5. The mangoes were sold at 4 for a dollar.

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

Amount spent
Mangoes	Chikoos	Oranges	Total
5 u	4 u	1 u	10 u

Total amount spent on fruits
= 5 u + 4 u + 1 u
= 10 u

10 u = 20

1 u = 20 ÷ 10 = 2

Amount that Jade spent on mangoes
= 5 u
= 5 x 2
= $10 

Total number of mangoes that Jade bought
= 10 x 4
= 40

Number of fruits bought
Mangoes	Chikoos	Oranges
1x5	2x5
	5x2	6x2
5 p	10 p	12 p

The number of chikoos bought is repeated.  Make the number of chikoos the same.  LCM of 5 and 2 is 10.

5 p = 40

1 p = 40 ÷ 5 = 8

Total number of fruits that Jade bought
= 5 p + 10 p + 12 p
= 27 p
= 27 x 8
= 216

(b)
Total number of chikoos that Jade bought
= 10 p
= 10 x 8
= 80

Total amount that Jade paid for the chikoos
= 4 u
= 4 x 2
= $8

Price of each chikoo
= 8 ÷ 80
= $0.10 

Answer(s): (a) 216; (b) $0.10
