Step 1: Identify the original price of the book, which is Rs. 150.
Step 2: Determine the discount percentage, which is 20%.
Step 3: Calculate the discount amount by multiplying the original price by the discount percentage: 150 * 20 / 100.
Step 4: Perform the calculation: 150 * 20 = 3000, then divide by 100 to get the discount amount, which is Rs. 30.
Step 5: Subtract the discount amount from the original price to find the sale price: 150 - 30.
Step 6: Perform the subtraction: 150 - 30 = Rs. 120.
