(A): Perfect squares between 1 and 93 = 1,4,9,16,25,36,49,64,81
Perfect cubes between 1 and 93 = 1,8,27,64
Possible values of N = 1, 64
Thus, first statement alone is not sufficient.
(B): Number of square roots between 1 and 93 = 1,2,3,4,5,6,7,8
Now, since it is divisible by 8, only one possible value of N exists,
∴ Statement B alone is sufficient.
The correct answer is (D) : If both the statements are INDEPENDENTLY sufficient to answer the given question.
