Let
\n" ); document.write( "Present age of Mother = m
\n" ); document.write( "Present age of Son = s\r
\n" ); document.write( "\n" ); document.write( "Given
\n" ); document.write( "=======
\n" ); document.write( "When the son was born mother was 27, means mother is 27 older than son
\n" ); document.write( "m=s+27..............(1)\r
\n" ); document.write( "\n" ); document.write( "8 years ago means we have to subtract 8 from their present ages
\n" ); document.write( "m-8=s-8\r
\n" ); document.write( "\n" ); document.write( "then mother was twice as old as son will be in 5 means we have add 5 in the age of the son 8 years ago
\n" ); document.write( "(m-8)=2((s-8)+5)
\n" ); document.write( "m-8=2s-16+10
\n" ); document.write( "m-8=2s-6
\n" ); document.write( "m=2s-6+8
\n" ); document.write( "m=2s+2...........(2)
\n" ); document.write( "==============================================
\n" ); document.write( "Put the value of m from (1) to (2)
\n" ); document.write( "s+27=2s+2
\n" ); document.write( "s-2s=2-27
\n" ); document.write( "-s=-25
\n" ); document.write( "Multiply by (-1) both sides
\n" ); document.write( "-s(-1)=-25(-1)
\n" ); document.write( "s=25
\n" ); document.write( "Put the value of s in (1)
\n" ); document.write( "m=s+27
\n" ); document.write( "m=25+27
\n" ); document.write( "m=52
\n" ); document.write( "Present age of Mother = m = 52 years old
\n" ); document.write( "Present age of Son = s = 25 years old
\n" ); document.write( "
\n" ); document.write( "
\n" );
