\n" ); document.write( "Let
\n" ); document.write( "Present age of Carmelo = c
\n" ); document.write( "Present age of Arwin = a\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Carmelo is 12 years older than arwin.
\n" ); document.write( "c=a+12........(1)
\n" ); document.write( "One-third of carmelo's aga is equal to one-half of arwin's age
\n" ); document.write( "c * 1/3=a * 1/2
\n" ); document.write( "c/3=a/2
\n" ); document.write( "2c=3a...........(2)
\n" ); document.write( "Put the value of c from (1) to (2)
\n" ); document.write( "2(a+12)=3a
\n" ); document.write( "2a+24=3a
\n" ); document.write( "2a-3a=-24
\n" ); document.write( "-a=-24
\n" ); document.write( "Multiply by by -1 both sides
\n" ); document.write( "a=24
\n" ); document.write( "Put the value of a in (1)
\n" ); document.write( "c=24+12
\n" ); document.write( "c=36\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Present age of Carmelo = c = 36
\n" ); document.write( "Present age of Arwin = a = 24\r
