The units digit of the product will be 6.
So the remainder can only be 1. (Corrected my mistake)


Ans A

A. 1
B. 2
C. 3
D. 4
E. 5


Only the unit's digit of the product will decide the remainder when divided by 5.

Hence, 6*7*8= will give units digit as 6
So, whatever be the number, if it ends in 6, the remainder after dividing with 5 will be 1.

Option A
