document.write( "(1)  Since 20% of the cards in the box are red and the number of blue card is 1/4 of the number of red cards,\r\n" );
document.write( "\r\n" );
document.write( "     it means that the number of red and green cards altogether is \r\n" );
document.write( "\r\n" );
document.write( "     0.2 +  = 0.25 = 25% of the total number of cards.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "(2)  Since among the remaining 150 cards the number of green cards is 2/3 of the number of white cards,\r\n" );
document.write( "\r\n" );
document.write( "     for the number of green cards x we have this equation\r\n" );
document.write( "\r\n" );
document.write( "         x = ,\r\n" );
document.write( "\r\n" );
document.write( "     which gives\r\n" );

document.write( "(3)  The remaining 150 cards comprise 100% - 25% = 75% = 0.75 of the total number of cards.\r\n" );
document.write( "\r\n" );
document.write( "     Hence, the total number of cards is   = 200 cards.\r\n" );
