Despite giving 23% discount on the book, Raj makes 10% profit. If Raj earns Rs.63 profit, then find the marked price of the book.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Rs. 900.
Let the Cost Price (CP) be ₹100
If Raj makes 10% profit, then:
Selling Price (SP) = 100 + 10 = ₹110
SP = 77% of MP = 0.77 × MP
SP = ₹110, so:
⇒ 0.77 × MP = 110
⇒ MP = 110/0.77 = ₹142.857...
If ₹10 profit → MP = ₹142.857
Then ₹63 profit → MP = (142.857 × 63)/10 = ₹900
