Given in question , Total CP of a horse and a carriage = $ 40,000.
Suppose the C.P. of horse be $ y, then
C.P. of carriage = $ (40000 – y)
Then,

∴		110 × y	+	(40000 - y) × 95	=	40000 × 101
		100		100		100

⇒ 110y + 3800000 – 95y = 4040000
⇒ 15y = 4040000 – 3800000
⇒ 15y = 240000

⇒ y =	240000	= $ 16000
