Question

Jyotsana bought 400 eggs at Rs 8.40 a dozen. At what price per hundred must she sell them so as to earn a profit of 15%?

Answer 1

Answer:

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.

Step-by-step explanation:

Solution

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.

Answer 2

Solution

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.
