In a three digit number, the hundred digit is 2 more than the tens digit and the units digit is 2 less than the tens digit. If the sum of the digits is 18, find the number?
Choose the correct choice from the following.
A) 867	B) 864	C) 385	D) 946	E) 549
864   864   Let the three digit numbers be 100a + 10b + c   a = b + 2   c = b - 2   a + b + c = 3b = 18 =&gt; b = 6   So a = 8 and b = 4   Hence the three digit number is: 864
