Question
Replace each * by the correct digit in the following:
✓
Answer
Here, we can we see that in the units digit, 6 - * = 7, which means that the value of * is 9, as 1 gets carried from 7 at tens place to 6 at unit place and 6 at unit digit becomes 16 then 16 - 9 = 7
Now, when 7 gives 1 to 6, it becomes 6, so 6 - 3 = 3.
Also, it can be easily deduced that in (8 - * = 6), the value of * is 2
