One thing you know for sure is the difference in
\n" ); document.write( "their ages is always the same.
\n" ); document.write( "Let \"+x+\" = Rahul's age now
\n" ); document.write( "Ram's age is \"+50+-+x+\"
\n" ); document.write( "The difference in their ages is \"+50+-+x+-+x+=+50+-+2x+\"
\n" ); document.write( "--------------------
\n" ); document.write( "Ram is saying \" when I was as old as you are \"
\n" ); document.write( "Rahul is \"+x+\" years old
\n" ); document.write( "If Ram is \"+50+-+x+\" now, how long ago was he \"+x+\" years old?
\n" ); document.write( "That would be \"+50+-+2x+\" years ago, since
\n" ); document.write( "\"+50+-+x+-%28+50+-+2x+%29+=++x+\"
\n" ); document.write( "-----------------------
\n" ); document.write( "How old was Rahul then?
\n" ); document.write( "He was \"+x+-%28+50+-+2x+%29+=+3x+-+50+\" years old
\n" ); document.write( "-----------------------
\n" ); document.write( "And Ram says \"I am twice that old\" so,
\n" ); document.write( "\"+50+-+x+=+2%2A%28+3x+-+50+%29+\"
\n" ); document.write( "\"+50+-+x+=+6x+-+100+\"
\n" ); document.write( "\"+7x+=+150+\"
\n" ); document.write( "\"+x+=+21.429+\"
\n" ); document.write( "\"+50+-+x+=+28.57+\"
\n" ); document.write( "Ram is about 28 and 7 months
\n" ); document.write( "Rahul is about 21 and 5 months
\n" ); document.write( "-------------------------
\n" ); document.write( "check:
\n" ); document.write( "The difference in their ages is \"+50+-+2x+\"
\n" ); document.write( "\"+50+-+2%2A%28+21.429+%29+=+50+-+42.858+\"
\n" ); document.write( "\"+50+-+42.858+=+7.142+\"
\n" ); document.write( "and
\n" ); document.write( "\"+28.57+-+21.429+=+7.141+\"
\n" ); document.write( "-----------------------
\n" ); document.write( "Hope my logic stands up
\n" ); document.write( "
