the sum of the digits of a three digit number is 14. The hundreds digit being 4 times the units digit. If 594 is subtracted from the number, the order of hundreds tens digits will be reversed. Find the number.\r
\n" ); document.write( "\n" ); document.write( "let the number be xyz\r
\n" ); document.write( "\n" ); document.write( "x+y+z=14\r
\n" ); document.write( "\n" ); document.write( "x=4z\r
\n" ); document.write( "\n" ); document.write( "Therefore 4z+y+z=14
\n" ); document.write( "y+5z=14..........................(1)\r
\n" ); document.write( "\n" ); document.write( "594 subtracted from the number\r
\n" ); document.write( "\n" ); document.write( "100x+10y+z-594 = 100z+10y+x\r
\n" ); document.write( "\n" ); document.write( "99x-99z=594\r
\n" ); document.write( "\n" ); document.write( "/99
\n" ); document.write( "x-z=6\r
\n" ); document.write( "\n" ); document.write( "But x=4z
\n" ); document.write( "4z-z=6
\n" ); document.write( "3z=6
\n" ); document.write( "z=2
\n" ); document.write( "if z=2 then x= 4z=>4*2=8\r
\n" ); document.write( "\n" ); document.write( "x+y+z=14
\n" ); document.write( "8+y+2=14
\n" ); document.write( "10+y=14
\n" ); document.write( "y=14-10
\n" ); document.write( "y=4\r
\n" ); document.write( "\n" ); document.write( "The number is xyz
\n" ); document.write( "842
\n" ); document.write( "
\n" );
