A says to B, \"I am five times old as you were, when I was as old as you are\".
\n" ); document.write( " The sum of their present ages is 64 years. Find their ages.
\n" ); document.write( ":
\n" ); document.write( "Let a = A's present age
\n" ); document.write( "Let b = B's present age
\n" ); document.write( ":
\n" ); document.write( "The sum of their present ages is 64 years.\"
\n" ); document.write( "a + b = 64
\n" ); document.write( "b = (64-a)
\n" ); document.write( ":
\n" ); document.write( "\"A says to B, \"I am five times old as you were, when I was as old as you are\".
\n" ); document.write( "a = 5(b - (a-b))
\n" ); document.write( "a = 5(b - a + b)
\n" ); document.write( "a = 5(2b - a)
\n" ); document.write( "a = 10b - 5a
\n" ); document.write( "a + 5a = 10b
\n" ); document.write( "6a = 10b
\n" ); document.write( "replace b with (64-a)
\n" ); document.write( "6a = 10(64-a)
\n" ); document.write( "6a = 640 - 10a
\n" ); document.write( "6a + 10a = 640

\n" ); document.write( "a = 40 yrs is A's present age

\n" ); document.write( "64-40 = 24 yrs is B's present age

\n" ); document.write( ":
\n" ); document.write( "Check this out: age difference 40 - 24 = 16 yrs
