Answer:
7
Step-by-step explanation:
Sum of odd places = 1+8+* = 9+*
Sum of even places = 0+3+2 = 5
Difference between 9+* and 5 should be 0,11,22,33...........
Let 9+*-5 = 0
=> 4+* = 0
=> * = -4 (value of * should not be negative.Therefore 9+*-5 ≠ 0)
Let 9+*-5 = 11
=> 4+* = 11
=> * = 11-4 = 7
Therefore the missing digit is 7.
