Given cost of eggs per dozen = Rs. 8.40
Cost of 1 egg = 8.40/12
= Rs. 0.7
Cost of 400 eggs = 400 x 0.7 = Rs. 280
Calculating the price at which Jyotsana should sell the eggs to earn a profit of 15%,
We get 15% of 280 + 280
= {(15/100) x 280} + 280
= {4200/100} + 280
= 42 + 280
= Rs. 322
So, Jyotsana must sell the 400 eggs for Rs. 322 in order to earn a profit of 15%. Therefore, the SP per one hundred eggs = Rs. 322/4 = Rs. 80.50.
