--------------
Let the number be 100a+10b+c
------
Equations:
a + b + c = 14
100a + 10b + c = 20b+14
b + c = a+12
---------------------------
Rearrange:
a + b + c = 14
100a - 10b + c = 14
-a + b + c = 12
--------------
Solve the system by any Method to get:
a = 1
b = 9
c = 4
----
Ans: Number is 194
