Usha spent $40 on some passion fruits, oranges and mangoes in the ratio of 2 : 5 : 1. The number of passion fruits was ²₅ the number of oranges. The ratio of the number of mangoes to the number of oranges was 3 : 1. The passion fruits were sold at 4 for a dollar.

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

Amount spent
Passion Fruits	Oranges	Mangoes	Total
2 u	5 u	1 u	8 u

Total amount spent on fruits
= 2 u + 5 u + 1 u
= 8 u

8 u = 40

1 u = 40 ÷ 8 = 5

Amount that Usha spent on passion fruits
= 2 u
= 2 x 5
= $10 

Total number of passion fruits that Usha bought
= 10 x 4
= 40

Number of fruits bought
Passion Fruits	Oranges	Mangoes
2x1	5x1
	1x5	3x5
2 p	5 p	15 p

The number of oranges bought is repeated.  Make the number of oranges the same.  LCM of 1 and 5 is 5.

2 p = 40

1 p = 40 ÷ 2 = 20

Total number of fruits that Usha bought
= 2 p + 5 p + 15 p
= 22 p
= 22 x 20
= 440

(b)
Total number of oranges that Usha bought
= 5 p
= 5 x 20
= 100

Total amount that Usha paid for the oranges
= 5 u
= 5 x 5
= $25

Price of each orange
= 25 ÷ 100
= $0.25 

Answer(s): (a) 440; (b) $0.25
