Jean spent $18 on some lemons, chikoos and pomegranates in the ratio of 2 : 3 : 1. The number of lemons was ²₅ the number of chikoos. The ratio of the number of pomegranates to the number of chikoos was 5 : 3. The lemons were sold at 2 for a dollar.

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

Amount spent
Lemons	Chikoos	Pomegranates	Total
2 u	3 u	1 u	6 u

Total amount spent on fruits
= 2 u + 3 u + 1 u
= 6 u

6 u = 18

1 u = 18 ÷ 6 = 3

Amount that Jean spent on lemons
= 2 u
= 2 x 3
= $6 

Total number of lemons that Jean bought
= 6 x 2
= 12

Number of fruits bought
Lemons	Chikoos	Pomegranates
2x3	5x3
	3x5	5x5
6 p	15 p	25 p

The number of chikoos bought is repeated.  Make the number of chikoos the same.  LCM of 3 and 5 is 15.

6 p = 12

1 p = 12 ÷ 6 = 2

Total number of fruits that Jean bought
= 6 p + 15 p + 25 p
= 46 p
= 46 x 2
= 92

(b)
Total number of chikoos that Jean bought
= 15 p
= 15 x 2
= 30

Total amount that Jean paid for the chikoos
= 3 u
= 3 x 3
= $9

Price of each chikoo
= 9 ÷ 30
= $0.30 

Answer(s): (a) 92; (b) $0.30
