Qrespected sir,
plz help me out for solving this % sum

A retailer shop's gross profit on a camera was 10% of the cost of the camera.if the store increase the selling price of the camera from $440 to $ 460 &the cost of the camera remained the same,then the shop's gross profit on the camera after the price increase was what % of the cost of the camera ? ------------------------ Let original price of the camera be "x" dollars Profit is 0.10x Selling price is $440 Equation: 1.1x = 440 x = $400 (original cost of the camera) ------------------ If the selling price is raised to $460 the profit is $60. The percent profit is 60/400 = 0.15 = 15% ================================================ Cheers, Stan H.
