A shopkeeper earns a profit of 17% on selling a book at 10% discount on the printed price. If the cost price is Rs 500, then the printed price (in Rs)
Let the printed price be Rs x
The shopkeeper gives a 10% discount, so the selling price (SP) becomes:
SP = x - 10% of x = 90% of x = 0.9x
The cost price (CP) is Rs 500, and the profit is 17%, so:
SP = CP + 17% of CP = 500 + 17% of 500 = 500 + 85 = Rs 585
Now equate the two expressions for selling price:
0.9x = 585
x = 585 / 0.9 = Rs 650
Answer: The printed price is Rs 650
