Question

Harish purchased 50 dozen bananas for 135rupees .five dozen bananas could not be sold ,because they were rotten at what prive per dozen should harish sell the remaining bananas so that he could make a profit of 20%

Answer 1

let remaining bananas are sold by= x rs

in the question data given by 50 dozensx 135 per dozen  so

50x135 = 6750

5 dozen is not sold so 45 dozen are sold

and harish earns 20% all over profit.

So equation will be

45x = 6750x120/100

after solving this

x= 180Rs

if he sells remaining 45 dozen at 180/dozen he will earn 20% profit.
