Question

is 6 digit number is shown below. Sum of its digit are hidden. If the number is divisible by 8, then which of the following number will be at the unit place?
[_,][ _,][ _,][3][5][_]
(a) only 2.
(b) only 4.
(C) only 6.
(d) only 8.
(E) both 2 and 6​

Answer 1

The answer is option (a) only 2

Because a number is divisible by 8 when the last three digits of the number are divisible by 8. Out of the 5 options if we put 2 at the end of 35 we get 352 which is divisible by 8. Hence the hidden 6 digit number is also divisible by 8.
