A little something to get the grey matter moving....
A number has five different digits, none of which is 0:
(A) The first plus the second equal the third digit;
(B) The third times 2 plus the second equals the fifth;
(C)The second times 2 equals the first;
(D) The first times 4 equals the fourth; and
(E) The fourth minus the second equals the fifth.
