The three digits of a number add up to 23. The number is divisible by 5. The leftmost digit is double the middle digit. What is the product of the three digits?	Pick:  A) 350  B) 720  C) 360  D) 380  E) 425
Say the three-digit number is abc.   The leftmost digit is double the middle digit --&gt; a=2b;   The number is divisible by 5 --&gt; c is either 0 or 5;   The three digits of a number add up to 23 --&gt; a+b+c=23   So, either a+b+c=2b+b+0=23 or a+b+c=2b+b+5=23. The first equation does not give an integer value of b, so it's not the case. From the second we get that b=6 --&gt; a=12 and c=5 --&gt; a*b*c=360.   Answer: 360.
