Average of 5 tests = 82%
\n" ); document.write( "Total of 5 tests = 5 * 82 = 410
\n" ); document.write( "Average of 6 tests to achieve 85%
\n" ); document.write( "Total of 6 tests = 6 * 85 = 510
\n" ); document.write( "510 - 410 = 100
\n" ); document.write( "Therefore he must score 100 for his 6th test.
