document.write( "\r\n" );
document.write( "Jamie bought 20 notebooks and 48 pens. 1 notebook cost 3 times the cost of the pen.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence 20 notebooks and 48 pens are equivalent to 20 + 48/3 = 20 + 16 = 36 notebooks.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus, you can think that she spent 1/4 of her money for 36 notebooks.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "After she spent 1/4 of her money, she left with 3/4 of her money.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "2/3 of 3/4 is  1/2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, she additionally spent 1/2 of her money for additional notebooks.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the number of additional notebooks is 2 times 36, i.e. 72.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus, in all, she bought 20 + 72 = 92 notebooks, altogether.      ANSWER\r\n" );
