The man buys a dozen or 12 cameras for $1800. They are sold at a profit of $36 each.

The initial cost of each camera is $1800/12 = $150. The profit made for the investment of $150 in buying a camera is $36. This gives the selling price as $150 + $36 = $186.

The profit as a fraction of the selling price is $36/$186 = 0.1935

In terms of percentage it is 0.1935*100 = 19.35%

The profit made as a percentage of the selling price is 19.35%.

 Aman buys a dozen cameras for $1800. He sells them at a profit of $36 each. Find his profit as a percentage of the selling price.

Buying price of one camera= 1800/12

=150 $

Selling price of one camera= 150+36

=186

Selling price $ 186   then profit   = $36

If selling price $100 then profit=(36 x 100)/186

=19.35

 Profit as a percentage of the selling price=19.35
