If for a certain quantity of books, the publisher has to pay Rs. 30,600 as printing cost, then what will be the amount of royalty to be paid for these books?
Answer: C
Let the total cost be T.
The printing cost is 20% of the total cost. So, 0.20 × T = Rs. 30,600.
T = 30600 / 0.20 = Rs. 153,000.
The royalty is 15% of the total cost.
Amount of royalty = 15% of 153,000 = 0.15 × 153,000 = Rs. 22,950.
