The sum of the digits of a 2 digit no. is 9, when the digits are reversed the new no. is 27 more than the original no. Find the no.
\n" ); document.write( "LET XY BE THE NUMBER...SUM OF DIGITS =X+Y=9.....................I
\n" ); document.write( "ITS VALUE =10X+Y
\n" ); document.write( "WHEN DIGITS ARE REVERSED WE GET YX...ITS VALUE = 10Y+X
\n" ); document.write( "DIFFERENCE BETWEEN THE 2 NUMBERS =27=10Y+X-10X-Y=9Y-9X=9(Y-X)
\n" ); document.write( "Y-X=3.............II
\n" ); document.write( "EQN.I+EQN.II....
\n" ); document.write( "2Y=9+3=12
\n" ); document.write( "Y=12/2=6
\n" ); document.write( "X=9-Y=9-6=3
\n" ); document.write( "THE NUMBER IS 36
\n" ); document.write( "
\n" );
