Question 136
If 550 copies are published and the transportation cost on them amounts to ₹8250, then the selling price of the book so that the publisher can earn a profit of 25% is:
Solution
Transportation cost of 1 book = $$\frac{8250}{550}=15$$
=> Percentage distribution on transportation cost = 10%
Thus, total cost price of a book = $$\frac{15}{10}\times100=Rs.$$ $$150$$
