A shopkeeper earns a profit of 17% on selling a book at 10% discount on the printed price. If the cost price is ₹500, then the printed price (in ₹) is :

650

    CP                            MP

( 100 - D%)              ( 100 + P%)   

( 100 - 10%)            ( 100 + 17%)

 90                                117

90 = ₹500

117 = \(\frac{500 × 117}{90}\) = ₹650
