A 24 Correct Answer Incorrect Answer
B 12 Correct Answer Incorrect Answer
C 20 Correct Answer Incorrect Answer
D 30 Correct Answer Incorrect Answer

Solution

We know that in the equation, (xn+ yn) where n is the odd number is completely divided by (x+y) Similarly, (1179+ 1379) is divisible by (11 + 13) i.e., 24 And (13)85+ (11)^85 is divisible by (13 + 11) = 24 Therefore the H.C.F is 24
