Sohini 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 percent?

Give me the solution of it.

In the U.S., we prefer "please" to "give me."

How do you think this problem can be solved?

Answered by Reiny
simplest way i can see:

purchase price = 400 at 8.40
or
100 at 2.10

profit of 15% of 2.10 = 1.15(2.10) = 2.415

Please do something
Answered by Damon
12 for 8.40

8.40/12 = 0.7 Rs/egg

0.7 * 1.15 = .805 Rs/egg

times 100 = 80.5

Answered by Amy
CP of 1 egg = 840/12 = 0.7 RS
CP of 400 eggs = 400*0.7 = 280 RS
CP of 400 eggs per hundred = 2.80 RS
Profit = 15/100*2.8 = .42 RS
SP = 280+.42 = 3.22 RS
