\n" ); document.write( "(A) 30 (B) 25 (C) 20 (D) 15 (E) 10
\n" ); document.write( "
Let number of weeks be W
\n" );
document.write( "No. of lessons Jack has in W weeks: 2W
\n" );
document.write( "No. of lessons Hannah has in W weeks: \"matrix%281%2C3%2C+%281%2F2%29+%2A+W%2C+or%2C+W%2F2%29\"
\n" );
document.write( "We then get: \"2W+=+W%2F2+%2B+15\"
\n" );
document.write( "4W = W + 30 ------- Multiplying by LCD, 2
\n" );
document.write( "4W - W = 30
\n" );
document.write( "3W = 30
\n" );
document.write( "W, or number of weeks in which Jack had 15 more lessons:  \n" );
