Correct Answer - Option 1 : 200
Given:
Marked Price = Rs. 300
Discount = 15%
pamphlet price = Rs. 15
Profit = 20%
Formula Used:
S.P = (100 – discount%)/100 × M.P
C.P = [100/(100 + profit%)] × S.P
Calculation:
Marked Price = Rs. 300
∴ Selling Price = {[(85/100) × 300] – 15}
⇒ [(85 × 3) – 15]
⇒ 255 – 15
⇒ Rs. 240
∴ Gain = 20%
∴ C.P = (100/120) × 240
⇒ 100 × 2
⇒ Rs. 200
∴ The Cost price of each book is Rs. 200.
