Paul is 12 years older than Colin. Caroline is 3 years younger than Colin. If the total of their ages is 87, how old is the youngest of them?
\n" ); document.write( "
After reading you should realize that Caroline is the youngest. Therefore, we need to find Caroline's age, and NO-ONE else's.\r
\n" );
document.write( "\n" );
document.write( "Let Caroline’s age be C
\n" );
document.write( "Then Colin’s is: C + 3, and Paul’s is: C + 3 + 12 = C + 15
\n" );
document.write( "We then get: C + C + 3 + C + 15 = 87
\n" );
document.write( "3C = 69
\n" );
document.write( "C, or Caroline is: \"highlight_green%28matrix%281%2C4%2C+69%2F3%2C+%22=%22%2C+23%2C+years-old%29%29\"
\n" );
document.write( "That's IT!! \n" );
