Question

I still not got the condition plz explain...

Eggs) * (Price) = 240

(Eggs + 2) * (Price - 0.5) = 240

Answer 1

a man sold his stack of eggs for Rs.240.if he had 2 dozen more ,he would have got the same money by selling the whole of 0.5 per dozen cheaper.how many dozen eggs does he sell?

Ok, I do not know what you mean by
" selling the whole of .5 per dozen cheaper".

Answer 2

Hi Aly -
use the solution we found previously

we obtained:

Rs240/D = (Rs240 + 0.5D + 1)/(D + 2)
Now solve for D:

Rs240 = D * (Rs240 + 0.5D + 1)/(D + 2)
So 240 = (240D + 0.5D^2 + D)/(D + 2)
240(D + 2) = (240D + 0.5D^2 + D)
240D + 480 = 240D + 0.5D^2 + D
480 = 0.5D^2 + D
D = 30

Try it:

Originally 30 * 8 = Rs240

Alternately 32 * 7.5 = Rs240

Some advice: You will need to know how to solve q quadratic equations if you are going to be successful with this type of problem.
