Question : 90 of 200

Marks: +1, -0

A salesman expects a gain of

13 \%

on his cost price. If in a month his sale was ₹ 791000 , what was his profit?

Solution:

Given, total selling price

=791000

Gain %

=13

To find the profit, first we have to find the cost price value.
Cost price

=\;{\;\text " Selling price "\; × 100}/{100+x}

where

x=

profit

\%

\;\text " Cost price "\; \;\; =\;{791000 × 100}/{100+13}

\;\; =\;{791000 × 100}/{113}=700000

Now, profit = Selling price - Cost price

=791000-700000=91000
