After taking 20% off, then there is a profit of 20%
\n" ); document.write( "Let \"+x+\" = the price before taking 20% off
\n" ); document.write( "\"+.2%2A%28+x+-+.2x+%29+=+100+\"
\n" ); document.write( "\"+.2%2A.8x+=+100+\"
\n" ); document.write( "\"+.16x+=+100+\"
\n" ); document.write( "\"+x+=+625+\"
\n" ); document.write( "\"+625+-+.2%2A625+=+.8%2A625+\"
\n" ); document.write( "\"+.8%2A625+=+500+\" is the price after discount
\n" ); document.write( "The MP ( marked price ) would be:
\n" ); document.write( "\"+1.2%2A500+=+600+\"
\n" ); document.write( "Rs. 600
\n" ); document.write( "Definitely get a 2nd opinion & check my math
