\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The answer to (1) is more than easy:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "    if one raisin bar is 12p more than one nut bar, then 9 raisin bars cost 12p times 9 more than 9 nut bars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    12p 9 times is 108p.      ANSWER to part (1)\r\n" );
document.write( "

\n" ); document.write( "\n" ); document.write( "Isn't it self-evident ? What is the sense to ask about obvious things ?\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "====================\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To answer question (2), put all 12 + 9 = 21 bars in a row.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Close to each nut bar place 12p (mentally).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then you will have 21 groups: 9 groups contain raising bars only, each group;\r
\n" ); document.write( "\n" ); document.write( " 12 groups contain nut bar and 12p, each group.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, you have 21 groups, and each of them \"costs\" the same amount.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To keep everything in equilibrium, you must add 12*12p = 144p to £5.28, giving you 528 + 144 = 672p.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Last step is to divide 672p by 21 to get the price of one raisin bar \"672%2F21\" = 32p.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is your ANSWER: one raisin bar costs 32p.
