Question

A man bought a horse and carriage for rupees 3,000. he sold the horse at a gain of 20% and the carriage at a loss of 20% thereby gaining 2% on the whole. find the cost of the horse..

Answer 1

Let's assume that the cost of the horse was x

now
selling price of horse = 1.2x
selling price of carriage = 0.8(3000-x)

and net selling price = 1.02*3000 =Rs3060

Now we can write
1.2x+0.8(3000-x)=3060
0.4x+2400=3060
x=1650

show the cost price of the horse was Rs1650
