Which position should a contender choose if he has to be the leader?
Explanation:
Let, f(n)represent the position of winner when n persons are standing in a circle.
f (n) = 2l + 1
where, n = 2m + l and 0 ≤ l < 2m
Now, n = 545
∴ n = 512 + 33
∴ n = 29 + 33
l = 33
∴ f (545) = 2 × 33 + 1 = 67
Hence, option (b).
