**A notebook is marked at ₹ 30. Find the price a student pays for a dozen notebooks if he gets a 15% discount**

Answer:

It is given that

M.P. of one notebook = ₹ 30

M.P. of one dozen notebooks = 30 × 12 = ₹ 360

Discount = 15%

We know that

Amount of discount = 15% of M.P.

It can be written as

= 15% of ₹ 360

By further calculation

= (15/100 × 360)

So we get

= (15/10 × 36)

= (3/2 × 36)

On further simplification

= 3 × 18

= ₹ 54

Price a student pays for a dozen notebooks = 360 – 54 = ₹ 306
