The Marked price of an article is 50% above Cost price.
\n" ); document.write( " When Marked price is increased by 20% & Selling price is increased by 20%, the profit doubles.
\n" ); document.write( " If original Marked price is 300, then what is the original Selling price ?
\n" ); document.write( ":
\n" ); document.write( "let x = the cost price
\n" ); document.write( "then
\n" ); document.write( "1.5x = 300
\n" ); document.write( "x = 300/1.5
\n" ); document.write( "x = $200 is the cost price
\n" ); document.write( ":
\n" ); document.write( "20% increase in marked price: 1.2(300) = $360
\n" ); document.write( "Another 20% increase to obtain the selling price: 1.2(360) = $432
\n" ); document.write( "\"the profit doubles. then what is the original Selling price ?\"
\n" ); document.write( "total profit (doubled): 432 - 200 = $232
\n" ); document.write( "\"1%2F2\"(232) = 116
\n" ); document.write( "200 + 116 = $316 is the original selling price
\n" ); document.write( "
