A salesman expects a gain of 13% on his cost price. If in a month his sale was 791000 Rs. , what was his profit?
[A]85659 Rs.
[B]97786 Rs.
[C]88300 Rs.
[D]91000 Rs.

91000 Rs.
Cost price $= \frac{791000\times 100}{113} = 700000Rs.$
$\therefore Gain = 791000 - 700000 = 91000 Rs.$
Hence option [D] is the right answer.
