Due to increase of 20% in the price of eggs, 2 eggs less are available for Rs.24. The present rate of eggs per dozen is ?
Rs.27.80
Incorrect AnswerExplanation:
Where we want to keep the expenditure same, There the Price ratio and Quantity ratio is in reverse order.
Price Ratio:-
100 : 120 => 5 : 6
Quantity Ratio:-
6 : 5
Decreased Value of Quantity => 1 unit ---------> 2 eggs
=> 5 units --------> 5* 2 = 10 eggs.
Now 10 eggs are bought in Rs.24.
So New(Reduced) price per egg is => 24/10 = 2.4 Rs./egg
Now the Price of 1 egg = Rs.2.4
Price of 12 eggs = 12 * 2.4 = 28.80 Rs.
