Question

A shopkeeper earns 40% profit on selling an object for Rs910.Find the cost price of that object.

Answer 1

Answer:

profit % = 40 %

s.p = Rs.910

c.p = ?

now ,

profit% = s.p -c.p / c.p x 100 %

or , 40c.p = (910 - c.p) x 100%

or , 40 c.p = 91000 - 100c.p

or , 140c.p = 91000

or ,c.p = 91000 / 140

therefore , c.p = Rs 650
