Algebra.Com's Answer #464269 by sachi(548) You can put this solution on YOUR website! The sum of digits of a 2 digit number is 10. \n" ); document.write( "let the ones digit=x then tenth digit=10-x \n" ); document.write( "the no is 10[10-x]+x \n" ); document.write( "when the digits interchange their position the no will be 10x+[10-x] \n" ); document.write( "The digits of the number interchange their places, when 36 is subtracted from the number. \n" ); document.write( "so 10x+[10-x]=10[10-x]+x-36 \n" ); document.write( "or 10x+10-x=100-10x+x-36 \n" ); document.write( "or 18x=54 \n" ); document.write( "or x=3 \n" ); document.write( "so the two digit number=10[10-x]+x=10[10-3]+3=73 \n" ); document.write( " |
