He sold all the small and medium papayas. He received $525 from selling ³₅ of the large papayas.

2. How much more did he collect from selling the medium papayas than the small papayas?

Small papayas	Medium papayas	Large papayas
	2x5	1x5
1x1		5x1
1 u	10 u	5 u

(a)
The number of large papayas is the repeated identity. Make the number of large papayas the same.  LCM of 1 and 5 is 5.

	Small papayas	Medium papayas	Large papayas
Before	1 u	10 u	5 u
Change	- 1 u	- 10 u	- 3 u
After	0	0	2 u

Number of large papayas that Neave sold
= ³₅ x 5 u
= 3 u

	Small papayas	Medium papayas	Large papayas
Number	1 u	10 u	3 u
Value	$4	$6	$7
Total value	4 u	60 u	21 u

Amount that Neave received from selling of ³₅ of the large papayas = 21 u
21 u = 525

1 u = 525 ÷ 21 = 25

Number of medium papayas at first
= 10 u
= 10 x 25
= 250

(b)
Amount that Neave collected more from selling the medium papayas than the small papayas
= 60 u - 4 u
= 56 u
= 56 x 25
= $1400

Answer(s): (a) 250; (b) $1400
