6241 is one answer , but see below.
Step-by-step explanation:
If the number is vwxy we have:
v = 3w
x + y = v - 1
w = x - 2
From equations 1 and 2:
v = 3(x - 2).
The only possible values of v are 3, 6 or 9.
If v = 3:- 3 = 3(3 - 2) so x = 3 also.
If v = 6:- 6 = 3(4 - 2) so x = 4.
If v = 9:- 9 = 3(5 - 2) so x = 5.
Now consider the first equation x + y = v - 1:-
If v = 3 then 3 + y = 3 - 1 giving y = -1 so v = 3 is not possible.
If v = 6 then 4 + y = 6 - 1 giving y = 1 which is a possible value.
If v = 9 then 5 + y = 9 - 1 giving y = 3 which is also possible.
If x = 4 w = 4 - 2 = 2
If x = 5 w = 5-2 = 3.
Thus the possible values are 6241 or 9353.
If all digits must be different the answer is 6241.
