Question

answer to become brilliant​

Answer 1

Answer:

Let the price of the book before discount be x

x - [x × (10/100)] = 180

or, x - x/10 = 180

or, (10x - x)/10 = 180

or, 9x = 180 × 10

or, 9x = 1800

or, x = 1800/9

or, x = 200

The price of the book before discount = 200

Option A is the correct answer.
