Vanessa spent $63 on some persimmons, chikoos and passion fruits in the ratio of 2 : 3 : 4. The number of persimmons was
25 the number of chikoos. The ratio of the number of passion fruits to the number of chikoos was 3 : 1. The persimmons were sold at 2 for a dollar.

- How much did each chikoo cost?

9 u |
Total amount spent on fruits
= 2 u + 3 u + 4 u
= 9 u
9 u = 63
1 u = 63 ÷ 9 = 7
Amount that Vanessa spent on persimmons
= 2 u
= 2 x 7
= $14
Total number of persimmons that Vanessa bought
= 14 x 2
= 28

The number of chikoos bought is repeated. Make the number of chikoos the same. LCM of 1 and 5 is 5.
2 p = 28
1 p = 28 ÷ 2 = 14
Total number of fruits that Vanessa bought
= 2 p + 5 p + 15 p
= 22 p
= 22 x 14
= 308
(b)
Total number of chikoos that Vanessa bought
= 5 p
= 5 x 14
= 70
Total amount that Vanessa paid for the chikoos
= 3 u
= 3 x 7
= $21
Price of each chikoo
= 21 ÷ 70
= $0.30
Answer(s): (a) 308; (b) $0.30
