Bill is three times as old as Mary. Bill is 48. How old will Bill be when he is twice as old as Mary?
\n" ); document.write( " ----------
\n" ); document.write( "Equations::
\n" ); document.write( "b = 3m
\n" ); document.write( "b = 48
\n" ); document.write( "----
\n" ); document.write( "So 3m = 48
\n" ); document.write( "And M = 16 (Mary's age now)
\n" ); document.write( "Therefore Bill = 3m = 3*16 = 48 (Bill's age now)
\n" ); document.write( "------
\n" ); document.write( "Equation::
\n" ); document.write( "48+x = 2(16+x)
\n" ); document.write( "48+x = 32 + 2x
\n" ); document.write( "x = 16 yrs
\n" ); document.write( "----
\n" ); document.write( "Bill will be twice Mary's age when Bill is 48+16 = 64
\n" ); document.write( "Mary will then be 16+x = 16+16 = 32
\n" ); document.write( "-------------------------
