Solution -
Price of 3 eggs = 9.10
Price of 1 egg = 9.10/3
Price of 12 (1 dozen) eggs = (9.10/3) × 12
= 36.40
Due to an increase of 30% in the price of eggs,
Price of 12 eggs = 36.40 (30/100)
= 10.92
Price of 1 egg = 10.92/12
= Rs. 0.91
Therefore,
The present rate per egg is 91 paise.
Hence,
The correct answer is option (a) 91 paise.
