let the number be ab \r
\n" ); document.write( "\n" ); document.write( "we have a+b=10\r
\n" ); document.write( "\n" ); document.write( "and 10a+b-18 is a multiple of 11 (because it has the same digits)\r
\n" ); document.write( "\n" ); document.write( "now since a+b=10 we have few possibilities (91,82,73,64,19,28,37,46) now subtract 18 from these nos and see which no is divisible by 11\r
\n" ); document.write( "\n" ); document.write( "we will get the answer as 73\r
\n" ); document.write( "\n" ); document.write( "73-18=55
\n" ); document.write( "
