A man bought a horse and a carriage for 3000. He sold the horse at a gain of 20% and the carriage at a loss 10%, there by gaining 2% on the whole. Find the cost of the horse.	Choose the correct choice from the following choices
A) 1000  B) 1200  C) 1500  D) 1700  E) None of these
Let the C.P. of horse = x   Then the C.P. of carriage = (3000 – x)   20% of x – 10% of (3000 – x) = 2% of 3000   ⇒ x⁄5 - (3000−x)/10=60   ⇒ 2x - 3000 + x = 600   ⇒ 3x = 3600 ⇒ x = 1200   Answer 1200
