The prices of two fruits sold at a supermarket is shown.

Fruit	Price
Pomegranates	4 kg for $14
Chikoos	2 kg for $5

1. Xavier bought an equal mass of pomegranates and chikoos and spent $24 more on pomegranates than on chikoos. What was the total mass of fruits that Xavier bought?
2. Min spent an equal amount of money on pomegranates and chikoos. In terms of their masses, what was the ratio of pomegranates to the ratio of chikoos Min bought?

(a)
LCM of 4 and 2 = 4

One set = 4 kg of pomegranates and 4 kg of chikoos

Number of sets of 4 kg of pomegranates
= 4 ÷ 4
= 1

Number of sets of 2 kg of chikoos
= 4 ÷ 2
= 2

Difference in price of pomegranates and chikoos in one set
= 1 x 14 - 2 x 5
= 14 - 10
= $4

Number of sets
= 24 ÷ 4
= 6

Mass of pomegranates and chikoos in one set
= 4 + 4
= 8 kg

Total mass of fruits bought
= 6 x 8
= 48 kg

(b)
LCM of 14 and 5 = 70

Number of sets of 4 kg of pomegranates to be bought with $70
= 70 ÷ 14
= 5

Mass of 5 sets of 4 kg of pomegranates
= 5 x 4
= 20 kg

Number of sets of 2 kg of pomegranates to be bought with $70
= 70 ÷ 5
= 14

Mass of 14 sets of 2 kg of chikoos
= 14 x 2
= 28 kg

Mass of pomegranates : Mass of chikoos 
20 : 28 _(÷4)
5 : 7

Answer(s): (a) 48 kg; (b) 5 : 7
