ON AN AIRPLANE THAT IS 2/3 FULL, 20% ARE GIRLS, ONE FOURTH OF PASSENGERS ARE WOMEN, 1/8 OF THE PASSENGERS ARE BOYS AND THERE ARE 68 MEN. HOW MANY SEATS ARE THERE ON THE PLANE?
\n" ); document.write( "----------------
\n" ); document.write( "Let the number of seats on the plane be \"x\".
\n" ); document.write( "Number of occupied seats = (2/3)x
\n" ); document.write( "-------------------
\n" ); document.write( "Girls = (1/5)(2/3)x = (2/15)x
\n" ); document.write( "Women = (1/4)(2/3)x = (1/6)x
\n" ); document.write( "Boys = (1/8)(2/3)x = (1/12)x
\n" ); document.write( "Men = 68
\n" ); document.write( "===================
\n" ); document.write( "EQUATION:
\n" ); document.write( "(2/15)x + (1/6)x + (1/12)x + 68 = (2/3)x
\n" ); document.write( "Multiply thru by 60 to get:
\n" ); document.write( "8x + 10x + 5x + 60*68 = 40x
\n" ); document.write( "17x = 60*68
\n" ); document.write( "x = 60*4 = 240 (Number of seats on the plane)
\n" ); document.write( "================
