The given number is divisible by 5.
\n" ); document.write( "So the unit place is either 0 or 5
\n" ); document.write( "First let us take the unit place to be 0.
\n" ); document.write( "Let the tenth place be x.
\n" ); document.write( "Given, hundreds digit that is 2 more than the tens digit.
\n" ); document.write( "So the hundreth place = x+2.
\n" ); document.write( "The sum of the digits = x+2+x+0 = 2x+2
\n" ); document.write( "The valve of the number = (x+2)*100+x*10+0
\n" ); document.write( " = 100x+200+10x
\n" ); document.write( " = 110x+200 \r
\n" ); document.write( "\n" ); document.write( "Given, the number is 43 times the sum of the digit
\n" ); document.write( " 110x+200 = 43*(2x+2)
\n" ); document.write( " 110x-86x = 86-200
\n" ); document.write( " 24x = -114
\n" ); document.write( " x = -114/24
\n" ); document.write( "This is not possible because x is an inteder.
\n" ); document.write( "Next,
\n" ); document.write( "let us take the unit place to be 5.
\n" ); document.write( "Let the tenth place be x.
\n" ); document.write( "Given, hundreds digit that is 2 more than the tens digit.
\n" ); document.write( "So the hundreth place = x+2.
\n" ); document.write( "The sum of the digits = x+2+x+5 = 2x+7
\n" ); document.write( "The valve of the number = (x+2)*100+x*10+5
\n" ); document.write( " = 100x+200+10x+5
\n" ); document.write( " = 110x+205 \r
\n" ); document.write( "\n" ); document.write( "Given, the number is 43 times the sum of the digit
\n" ); document.write( " 110x+205 = 43*(2x+7)
\n" ); document.write( " 110x-86x = 301-205
\n" ); document.write( " 24x= 96
\n" ); document.write( " x= 96/24
\n" ); document.write( " x=4
\n" ); document.write( "So the tenth place = 4.
\n" ); document.write( "So the hundreth place = x+2 = 4+2 = 6
\n" ); document.write( "Therefore the given number is 645
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
