(A) 130 acres
(B) 135 acres
(C) 145 acres
(D) 160 acres
(E) 180 acres


The area of Farm A = x acres;
The area of Farm B = x-15 acres.

Total output of Farm A = 300x kgs;
Total output of Farm B = 350(x-15) kgs.

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

Answer: C.

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.
