Question

due to an increase of 30% in the price of eggs 3 eggs less are available for rupees 7.80 what is the present rate of eggs for dozen

Answer 1

Let Original price per Egg was X.

Increased Price = X + 30% of X = 1.3X
Now,

(7.80/X ) - (7.80 /1.3X) = 3

On solving, we get,

X = 0.6
Price per egg was Rs. 0.6 .
Present price = 1.3X = 1.3 * 0.6
Present price for 12 eggs = 1.3 * 0.6 * 12 = Rs. 9.36.
