Let number of children be C\r\n" );
document.write( "As there were 15 girls, number of boys = C - 15\r\n" );
document.write( "With average number collected by girls being 20, total collected by girls = 15(20) = 300\r\n" );
document.write( "With average number collected by boys being 14 more than each girl's average collection, or 34 (20 + 14),\r\n" );
document.write( "total collected by boys = 34(C - 15) = 34C - 510\r\n" );
document.write( "Since average number collected was 28, we get: 300 + 34C - 510 = 28C\r\n" );
document.write( "300 - 510 = 28C - 34C\r\n" );
document.write( "- 210 = - 6C\r\n" );
document.write( "Number of children, or
