102.

If the number 91876 * 2 is completely divisible by 8, then the smallest whole number in place of * will be:

 [A]. 1 [B]. 2 [C]. 3 [D]. 4 [E]. None of these

Explanation:

Then number 6x2 must be divisible by 8.

x = 3, as 632 is divisible 8.

 Aparna said: (Jul 2, 2015) Is it last 3 digits or 2 digits please tell me?

 Sivakumar.K said: (Jul 8, 2015) To substitute x=0, x=1, x=2, x=3....x=9. When x=3 to substitute in between "6x2" is completely divisible by 8 and it's not given remaining value, if you have any doubt to substitute x=0 up-to 9 in between "6x2".

 Sasi said: (Sep 21, 2015) Last 3 digits are divisible by 8. When put x=3. Other can't exist.

 Chan said: (May 31, 2016) Hi @Sasi. 9187632 is completely divisible by 8. Once again check it.

 Ramesh said: (Oct 12, 2016) 91876 x 2 is divisible by 8. 9 + 1 + 8 + 7 + 6 + x + 2 is divisible by 8. 33 + x is divisible by 8. So smallest value of x = 7 is divisible by 8. So the answer is none of above.

 D,Virajini said: (May 30, 2017) How did you check the answer if it is 3?

 D.Virajini said: (May 30, 2017) I agree with the answer @Ramesh.

 Pankil said: (Jun 6, 2017) 6 x 2 (where x=7 also divisible by 8) and 9187672 also divisible by 8. So that, we can get an answer with a Two-way number.

 Rinkal said: (Dec 10, 2017) I agree with answers @Ramesh.

 Dhara said: (Mar 28, 2018) Explain the solution, please.

 Vinod said: (May 27, 2018) The given no is completely divided by 8 only when last three digits are completely divided by 8. here last three digits are 6*2. If we put 3 in place of * then it will completely be divided by 8. Hence 3 is the answer. Hope all got it now.
