Question

A publisher sells a book for ₹168 at a profit of 20%. If his cost of production increases by 30% , what should be the increase in the price of the book so that his percentage profit remains the same.

Answer 1

Answer:

Ans: Rs 50.40

Step-by-step explanation:

let the original price = x  

so selling price  = 20% of x + x = 168

which gives x  = 140

Now this increases by 30%  

New production cost = 1.3(140) = 182

profit of 20% => the selling price = 1.2(182) = 218.40

so the increase in price = 218.40-168 = Rs 50.4
