20.476 ** 0 is divisible by both 3 and 11. The non-zero digits in the hundred's and ten's places are respectively?
A.7 and 4
B.7 and 5
C.8 and 5
D.None of Above
Answer:  Option  C
Explanation:

Let the given number be 476 xy 0.

Then (4 + 7 + 6 + x + y + 0) = (17 + x + y) must be divisible by 3.

And, (0 + x + 7) - (y + 6 + 4) = (x - y -3) must be either 0 or 11.

x - y - 3 = 0   ==> y = x - 3

(17 + x + y) = (17 + x + x - 3) = (2x + 14)

==> x= 2 or x = 8.

 x = 8 and y = 5.
