**Hint:**The market price and the selling price of a vendor is given in the question, simply use the direct formula for discount percentage to calculate the discount percentage provided by the vendor to the consumer.

**Complete step by step solution:**

The market price given in the question M.P = Rs1400

The selling price that is the price at which the vendor is selling the item to the customer is given in question S.P= Rs1274.

Now Discount given is the difference between the market price and the selling price.

$ \Rightarrow $Discount = M.P - S.P…………………… (1)

Putting values in equation (1) we get

Discount = 1400-1274

$ \Rightarrow $Discount = 126Rs

Now Percentage(x) =$\dfrac{x}{{total}} \times 100$ (Generalized formula)

Thus Discount percentage = $\begin{gathered}

$ \dfrac{{{\text{Discount}}}}{{M.P}} \times 100 $

Substituting the values we get

Discount % = $\dfrac{{126}}{{1400}} \times 100$

**On solving we get discount % = 9 %**

**Note:**Whenever we face such types of problems the key concept to remember is that the discount provided by a vendor or a businessman to his customers is always the difference between the market price and the selling price, thus extending this similar concept we can easily find the discount percentage.
