Question : A man bought 20 dozen eggs for Rs. 720. What should be the selling price of each egg if he wants to make a profit of 20%?
Option 1: Rs. 3.25
Option 2: Rs. 3.30
Option 3: Rs. 3.50
Option 4: Rs. 3.60
Correct Answer: Rs. 3.60
Solution :
The cost price of 20 dozen eggs = Rs. 720
Cost of 1 egg = $\frac{720}{20×12}$ = 3
Selling price at 20% profit $=\frac{100+\text{profit %}}{100}$ × Cost price $=\frac{120}{100}×3 = 3.60$
Hence, the correct answer is Rs. 3.60.
