The positive integer n is divisible by 25. If \sqrt{n} is greater than 25, which of the following could be the value of n/25 ?

(A) 22 (B) 23 (C) 24 (D) 25 (E) 26

since [square_root]n[square_root] is greater than 25 then our n is also greater than 25..i will try using the try and error method..lets say the value of n/25 =22,then n=550..[sqaure_root]550[sqaure_root] is less than and i guess it wont it wont work..going through all options integer 26 proved worth for an answer by satisfying the following points;it was a result of a division between positive integer n and 25 i.e integer n (650)is a multiple of 25 whose sqaure root is greater than 25..hence option E serves as the answer.

\sqrt{n}>25 --> n>25^2.

Divide both parts by 25: \frac{n}{25}>\frac{25^2}{25} --> \frac{n}{25}>25. The only answer choice that is greater than 25 is 26.

Answer: E.

Hello,

Maybe I don't understand something here, but how can 26/25 be more than 25? 26/25 is 1.04. Can you please explain.

Ayselka,

I know it looks confusing but the question was what is a possible value for \frac{n}{25} not "what is a possible value for n." Thus, \frac{n}{25}=26, n=650 in this scenario. I hope that helps, and good luck!

Hello,

I am confused on how to comprehend this question. I understand we are not looking for the value of n and that we are looking for the value of n/25, however, how are you dividing both sides of the inequality: n>25^2 by 25?

What do you mean by "how"? Just divide both sides of n>25^2 by 25.

Apologies... I meant "why" not "how". However, I do know now what they are asking. I guess the way OG presents the question didn't seem very linear to me so I was confused.
