Question

9. A bookseller sells a dictionary for 877.80 making 4.5% profit. At what price should he sell the dictionary to make 6% profit? ​

Answer 1

Answer:

first of all we have calculate purchase price because profit% calculated on purchase price..

purchase price=selling price*100/100+rate

purchase price=877.80*100/100+4.5 or 87780/104.5=840

now desired profit =6% on purchase price

desired profit=840*6%=50.4

desired selling price= 840+50.4=890.4
