You can put this solution on YOUR website!
7 years ago Somu was 3 times as old as Ram was at that time.
\n" ); document.write( "s - 7 = 3(r-7)
\n" ); document.write( "s - 7 = 3r - 21
\n" ); document.write( "s = 3r - 21 + 7
\n" ); document.write( "s = 3r - 14
\n" ); document.write( ":
\n" ); document.write( "If Somu is now 5 years older than Ram,
\n" ); document.write( "s = r + 5
\n" ); document.write( "replace s with (r+5) in the first simplified equation
\n" ); document.write( "(r+5) = 3r - 14
\n" ); document.write( "5 + 14 = 3r - r
\n" ); document.write( "19 = 2r
\n" ); document.write( "r = 19/2
\n" ); document.write( "r = 9.5 yrs old
\n" ); document.write( "then \"how old is Somu?\"
\n" ); document.write( "s = 9.5 + 5
\n" ); document.write( "s = 14.5 yrs old
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "These problems usually have integer solutions, check this in the statement
\n" ); document.write( "\"7 years ago Somu was 3 times as old as Ram was at that time
\n" ); document.write( "14.5 - 7 = 3(9.5 - 7)
\n" ); document.write( "7.5 - 3(2.5)
\n" ); document.write( "7.5 = 7.5, confirms our solution
\n" ); document.write( " :
