Farm B in total harvested 2000 kgs of wheat more than Farm A: 300x+2000=350(x-15) --> x=145 acres.

Answer: C.


I added 2000 to Farm B and was wondering what is wrong . I need a break from studies this evening .
PS: changed the Q to sub600.

thanks Bunuel


I assume that you calculated total output for farm B = 350*(x -15), and then added 2000 to it, Is that correct?
Because the question says: Farm B in total harvested 2000 kgs of wheat more than Farm A ==> Total output of farm A less than that of farm B

==> Total output of farm A + 2000 = Total output of farm B
--OR--
==> Total output of farm A = total output of farm B - 2000

Hope it's clear.
