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

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.

n should be divisible by 25 & \(\sqrt{n} > 25\)

\(So, n^2 > 625\)

Looking at all the options, only 26 fits in

Answer = E

Hello,

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

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.

the questions says n = 5*5*k (as its divisible by 25)
and then asks to find out possible value of K.

now it also says (n^0.5) > 25
which means 5* (k^0.5) > 25
squaring both sides we get K > 25.

Only possible ans is 26!

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.

Another explanation may be:

n/25 is an integer and the Square root of n is greater than 25, so:

n > 25 * 25

The first number that is more than 25*25 and divisible by 25 is 25*25 + 25 -> 25*25 + 25/25 = 25 + 25/25 = 26

N is divisible by 25 means that N is a muplitple of 25. So, could be 25*1=25, 25*2=50 etc etc.

Only this sentence helps you reject A,B,C, as they already are less than 25.

The second sentence says:
SQRTN>25, so
N> SQRT25 --> N> 625

N/25= 625/25= 25. So, N needs to be greater than 25. Only possible option is ANS E

And also let me add this small piece of advice: when you see greater than flag it somehow (circle it, underline it, write down
greater than, "GT" or whatever).
Than because in this case for example, managing to come to a solution could direct you to answer option D, as this was your result. However, the question wanted sth more than your result (greater than). It is a pitty to give the wrong answer like this...

We can solve this problem by translating the given information into math equations. We are first given that the positive integer n is divisible by 25. Translating this we have:

n/25 = integer

We are next given that the square root of n is greater than 25. So we can say:

√n > 25

Next we eliminate the square root by squaring both sides.

n > 25^2

n > 625

Since n must be a multiple of 25 and now we know it must be greater than 625, n/25 must be greater than 625/25, or 25. The only number greater than 25 in the answer choices is 26, so the answer must be E

Answer is E.

Hi!

A question on this please.

The Tag says this is a OG question. I am using OG-2016 and could not find this question. Does this mean that this is part of an older OG? Also, does this mean that the later OG's may not contain some of the questions contained in Older OG's? Just curious, so that I don't miss out on any OG questions while practicing.

Hello Bunuel

In an inequality like in the above, when should we cancel variables or values on both sides or take their square roots and when should we bring them on one side of the inequality to solve?

n is divisible by 25 that means n has at least 5^2 as its prime factors.

Also it's given that sq. root of n>25
Squaring both the sides, we get:

n>625
So n/25 has to be greater than 25 (because 625/25= 25 but n is > than 625).

E it is

Since \(\sqrt{n}\) > 25

-> n > 25^2
-> n> 25*25

Also n is a multiple of 25.

26*25, 27*25, 28*25,....................

So n = 26
