Let the cost price of horse be x and carriage be y

x+y = 8000

Also, 1.1x + 0.9y = 8000*(102.5/100) = 8200

solving the above two equations we get, x = 5000 and y = 3000

Fastrac method

Apply: net gain% – loss%: gain% – net gain%:: CP of horse:CP of carriage = 5:3

Therefore, CP of horse is 5000

Today’s problem

A loss of 19% gets converted into a profit of 17%, when the selling price is increased by $162. Find the cost price.
