Question

The printed price of books is Rs. 40 and it was sold for Rs. 35.20. What is the
rate of discount.​

Answer 1

Answer:

12%

Step-by-step explanation:

Let the rate of discount be x /100

So , the equation is

x/100 × 40 = 35.20

So , 40x /100 = 35.20

4x /10 = 35.20

x = 35.20 × 10 /4

x = 88%

So 100 - 88 = 12

Therefore a discount of 12% was given.
