\n" ); document.write( "Krutika is 11 years older than Gordon. Pip is 12 years younger than Gordon. If the total of their ages is 77, how old is the youngest of them?
\n" ); document.write( "

You don't have to determine all their ages to find the youngest's.
\n" );
document.write( "It's quite obvious that of the 3, Pip is the youngest
\n" );
document.write( "Let Pip's age be P
\n" );
document.write( "Then Gordon's is P + 12, and Krutika's is P + 12 + 11, or P + 23
\n" );
document.write( "We then get: P + P + 12 + P + 23 = 77
\n" );
document.write( "3P + 35 = 77
\n" );
document.write( "3P = 42
\n" );
document.write( "Pip, or  \n" );
document.write( "

\n" );
