Given that marked price of a book is ₹270, what is the cost of paper to publish a single copy of the book if the marked price of a book is 20% more than its cost price?

Accepted Answer

Step 1: Let the cost price (CP) of the book be x.

Step 2: Marked price (MP) is 20% more than CP, so MP = x + 0.20x = 1.20x.

Step 3: Given MP = ₹270, so 1.20x = 270 => x = 270 / 1.20 = ₹225.

Step 4: Paper cost is 25% of the cost price.

Step 5: Cost of paper = 25% of ₹225 = (25/100) * 225 = ₹56.25.

Double-checking calculations:
- CP = ₹225
- Paper cost = 25% of 225 = ₹56.25

Therefore, the correct answer is ₹56.25 (option 2).
