Initial ratio = 4/5 or 8/10 or 16/20 or 32 /40 etc\r
\n" ); document.write( "\n" ); document.write( "taking away 6 cars from each of above ratios\r
\n" ); document.write( "\n" ); document.write( "4/5 -6 not possible\r
\n" ); document.write( "\n" ); document.write( "8/10 - 6 = 2/10 =1/5 not desired ratio\r
\n" ); document.write( "\n" ); document.write( "16/20 -6 = 10/20 =1/2 desired ratio\r
\n" ); document.write( "\n" ); document.write( "therefore initially 16 cars, and 20 SUV's in lot
\n" ); document.write( "
