If 4 students sit on each bench,
\n" ); document.write( "Number of benches sat on= x/4
\n" ); document.write( "Total number of benches available= (x/4)+3
\n" ); document.write( "If 3 students sit on each bench,
\n" ); document.write( "Number of benches needed= x/3
\n" ); document.write( "3 students are left standing
\n" ); document.write( "Thus, 1 bench is needed
\n" ); document.write( "Therefore, number of benches available= (x/3) -1
\n" ); document.write( "Thus,
\n" ); document.write( "(x/4)+3 = (x/3)-1
\n" ); document.write( "x/4 + 3= x/3 – 1
\n" ); document.write( "x/4 – x/3 = -1-3
\n" ); document.write( "3x/12 – 4x/12 = -4 (L.C.M)
\n" ); document.write( "-x/12 = -4
\n" ); document.write( "-x = -4*12
\n" ); document.write( "-x = -48
\n" ); document.write( "so, x=48 \r
\n" ); document.write( "\n" ); document.write( "Number of students in the class = x = 48
\n" ); document.write( " \n" ); document.write( "
\n" );
