A man bought a horse and a carriage for Rs. 3000. He sold the horse at a gain of 20% and the carriage at a loss of 10%, thereby gaining 2% on the whole. Find the cost of the horse.	Choose the correct choice
A) 2200	B) 1800	C) 1200	D) 1000	E) 1500
Let the C.P of the horse be Rs. X, Then, C.P of the carriage = Rs.(3000- x).   20% of x - 10% of ( 3000-x ) =2% of 3000 = 60,   x/5 - ( 3000-x )/10 = 60, 3x - 3000 = 600, 3x =3600, x = 1200.   Hence, C.P of the horse = Rs. 1200   ANSWER:1200
