\n" ); document.write( "At one point in time, their ages were: M = 30; B = x; K = 2x. (Kenny was twice Bala's age when Mike was 30).

\n" ); document.write( "At another point in time, their ages were: M = 2y; B = 21; K = y. (Mike was twice Kenny's age when Bala was 21).

\n" ); document.write( "The number of years between those two times is the same for each of them:

\r\n" );
document.write( "30-2y = x-21 = 2x-y
\r\n" );
document.write( "30-2y = x-21  -->  x+2y = 51; x-21 = 2x-y  -->  y-x = 21
\r\n" );
document.write( "x+2y = 51  and  y-x = 21  -->  3y = 72  -->  y = 24

\n" ); document.write( "So Mike was 48 and Kenny was 24 when Bala was 21.

\n" ); document.write( "So the difference between Mike's age and Bala's age is 27 years.

\n" ); document.write( "So when Mike is 62, Bala will be 35. \n" ); document.write( "

\n" );
