(We know:
(i) If the one's place of number is 2, then the given whole no. will be divisible by 2.
(ii) If the total of given number is divisible by 3, then the
whole no. will be divisible by 3.
(iii) If the given no. is divisible by 2 & 3, then the given no. will be divisible by 6.)
So, in the solution the given number is " 5*2 ".
Now we substitute the first option [A] 2, in " * " place.
The one's place is "2" so that no. was divisible by 2.
Next (5+2+2) = 9. so the given no. was divisible by 3.
Therefore, the number was divisible by 6.
