An article is purchased for Rs. 450 and sold for Rs. 495. Find the gain percent?

A) 10%

B) 20%

C) 25%

D) 30%

Given that: C.P=450 & S.P=495

When S.P is greater than C.P, we get Profit

Profit=S.P-C.P

Profit=495-450

Profit = 45 

Now ,

Gain% = [100*Gain]/C.P

             = [100*45]/450

             = 10%
