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 30, find the number?
Pick one.
A) 11201
B) 12102
C) 12081
D) 12108
E) 10126
12108   12108   Let the three digit numbers be 100a + 10b + c   a = b + 2   c = b - 2   a + b + c = 3b = 30 =&gt; b = 10   So a = 12 and b = 8   Hence the three digit number is: 12108
