Max marks = 120 + 150 + 180 = 450\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let us assume that Susant scored x marks in Mathematics.
\n" ); document.write( "Total marks scored = 72 + 70 + x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Percentage of marks scored by Susant = \"%28142%2Bx%29%2A100%2F450=2%28142%2Bx%29%2F9\"
\n" ); document.write( "But this percentage is given to be as 60.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, \"60=2%28142%2Bx%29%2F9\"
\n" ); document.write( "\"270=142%2Bx\"
\n" ); document.write( "\"x=128\"
\n" ); document.write( "
