There are many benefits to timing your practice, including:

1) gives you 1<n<25 and 2) gives you 10<n<24. Both statements have many possibilities

The question stem says the sqrt(n) is a positive integer. So, n has to be a perfect square. The only perfect square that lies in the range 10<n<25 is 16.

Agree with B, but isn't it a nonsence to say that sqrt(n) is positive?

No - As square root of 16 can be 4 or -4. I think you are confusing this with square root of a negative number which is not defined. Bunuel can you please confirm if my logic is correct??

From the Official Guide:

A square root of a number n is a number that, when squared, is equal to n. Every positive number n has two square roots, one positive and the other negative, but √n denotes the positive number whose square is n. For example, √9 denotes 3.

So, √n is always greater than or equal to zero.
