A and B undertook to do a piece of work for $4500. A alone could do it in 8 days and B alone in 12 days. With the assistance of C they finished the work in 4 days. Then C’s share of the money is:

As we know that ,
Given that :- Total Payment = $4500

C alone can do the work in	1	-		1	+	1		=	1	-	5	=	6 - 5	=	1	i.e., 24 days
	4			8		12			4		24		24		24

Ratio of wages =	1	:	1	:	1	:	=	3 : 2 : 1
	8		12		24

C’s share =	C’s ratio	× Total amount
	Sum of all ratios

C’s share =	1	× 4500 = $750.
