\n" ); document.write( "When Bob was 12, his sister was half his age, which is 6.

\n" ); document.write( "When Bob was 12, his grandmother was 5 times his age, minus half his sister's age: 5(12)-(1/2)6 = 60-3 = 57.

\n" ); document.write( "His grandmother is now 60, so Bill was 12 3 years ago.

\n" ); document.write( "ANSWER: Bob is now 15.
