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

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

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

Number of large mangoes that Zeph sold
= ³₅ x 5 u
= 3 u

	Small mangoes	Medium mangoes	Large mangoes
Number	1 u	10 u	3 u
Value	$2	$3	$8
Total value	2 u	30 u	24 u

Amount that Zeph received from selling of ³₅ of the large mangoes = 24 u
24 u = 96

1 u = 96 ÷ 24 = 4

Number of medium mangoes at first
= 10 u
= 10 x 4
= 40

(b)
Amount that Zeph collected more from selling the medium mangoes than the small mangoes
= 30 u - 2 u
= 28 u
= 28 x 4
= $112

Answer(s): (a) 40; (b) $112
