The sum of three consecutive multiples of 3 is 72. What is the largest number?	Choose one
A) 21  B) 24  C) 27  D) 36  E) 42
Let the numbers be 3x, 3x + 3, 3x + 6   Then, 3x + 3x + 3 + 3x + 6 = 72 ===&gt; 9x = 63 ==&gt; x = 7.   so the largest number is 3x + 6 = 27.   hence the correct answer is option 27) 27.
