What will be remainder when (6767 + 67) is divided by 68 ?
1
63
66
67
Answer: Option
Explanation:

(xn + 1) will be divisible by (x + 1) only when n is odd.

(6767 + 1) will be divisible by (67 + 1)

(6767 + 1) + 66, when divided by 68 will give 66 as remainder.

(67^67+67)/68,
n(1^n +1)/68,
67(1^67+1)/68,
67(1+1)/68 = give reminder 66.

1 IS NOT DIVISIBLE BY 6 & 8.

(6+3) =9 -> 9 is not divisible by 6 & 8.
(6+7) -> 13 is not divisible by 6 & 8.
(6+6) -> 12 is divisible by 6 & 8 ===> ANSWER.

@All.

Here is the solution;
67 * 2 - 68 = remainder = 66.
Valid for any type of formation like the given one.
n*2-(n+1) = remainder.

Here, we can use n^n+n = (n+1) (n^n+1)/(n+1) + (n-1).

As division n=p*q+r.

(x^n - a^n) is divisible by (x - a) for all values of n.
(x^n - a*n) is divisible by (x + a) for even values of n.
(x^n + a^n) is divisible by (x + a) for odd values of n.
