3 tests with an average of 85
\n" ); document.write( "= total marks of 3 * 85 = 255
\n" ); document.write( "Two more tests getting 100 in each
\n" ); document.write( "= 255 + 200 = 455
\n" ); document.write( "455/5 = 91
\n" ); document.write( "This is her new average.
\n" ); document.write( "Hope this helps.
