Let the cost of paper for a single book be Rs. n.
Then, 120 : 25 = 180 : n => n = Rs. (25x180)/120
= Rs. 37.50 .
If 5500 copies are published and the transportation cost on them amounts to Rs. 82500, then what should be the selling price of the book so that the publisher can earn a profit of 25%?
Answer & Explanation:
Answer: Option A
Explanation:
For the publisher to earn a profit of 25%, S.P. = 125% of C.P.
Also Transportation Cost = 10% of C.P.
Let the S.P. of 5500 books be Rs. x.
Then, 10 : 125 = 82500 : x => x = Rs.(125x82500)/10= Rs. 1031250.
Therefore S.P. of one book = Rs. 1031250/5500= Rs. 187.50 .
