The three digits of a number add up to 20. The number is divisible by 5. The leftmost digit is double the middle digit. What is the product of the three digits?  Select
A) 175 B) 250 C) 78 D) 225 E) 125
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 20 --&gt; a+b+c=20   So, either a+b+c=2b+b+0=20 or a+b+c=2b+b+5=20. The first equation does not give an integer value of b, so it's not the case. From the second we get that b=5 --&gt; a=10 and c=5 --&gt; a*b*c=250.   Answer: 250.
