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
