Q. A shopkeeper bought 50 books at the rate of Rs. 30 per book. He sold them for Rs. 1610. Find profit or loss percent. 

Solution: 

C.P of one book = Rs. 30

C.P of 50 books = Rs. 50 ｘ Rs. 30 = Rs. 1500

Sale price S.P = Rs. 1610

As S.P is greater than C.P, there is a profit and profit percent general formula is

Profit percent = `frac {Rs. 1610 - Rs. 1500}{Rs. 1500}times 100`

Profit percent = `frac {Rs. 110}{Rs. 1500}times 100`
