If you make a Venn diagram of those who FAILED, then you have 20% only failing math, 10% only failing English and 15% failing both. That means 45% of the students failed at least one. That then means that 55% of the students passed both...
\n" ); document.write( "Now call x the total number of students...we write
\n" ); document.write( ".55x = 495
\n" ); document.write( "x = 900 total students
\n" ); document.write( "
\n" );
