1) Not sufficient because n could be 4, 16, 36, 64, etc.

2) Doesn't between 2 and 100 mean 3 to 99? (I thought between means do not include the end points). Statement 2 says the cube of root n is an integer. Woudln't the cube root of 27 be included? as well as the cube root of 64?

The OG guide says there is only one such value of n between 2 and 100, which is 64.

Can someone please help me understand this question.

I have a question about statement 2.....

If n is an integer between 2 and 100 and if n is also the square of an integer, what is the value of n?

1) n is even

2) The cube root of n is an integer

1) Not sufficient because n could be 4, 16, 36, 64, etc.

Thanks for help in advance.

The question stem says that the "n" is square of an integer; 27 is not a square of any integer. Leaves us with just 64, which is 8^2. _________________

Hello from the GMAT Club BumpBot!

Thanks to another GMAT Club member, I have just discovered this valuable topic, yet it had no discussion for over a year. I am now bumping it up - doing my job. I think you may find it valuable (esp those replies with Kudos).

If n is an integer between 2 and 100 and if n is also the square of an integer, what is the value of n?

Given: n is a perfect square between 2 and 100 (a perfect square is an integer that can be written as the square of some other integer, for example 16=4^2, is a perfect square).

(1) n is even --> n can be any even perfect square in the given range: 4, 16, 36, ... Not sufficient.

(2) The cube root of n is an integer --> so n is also a perfect cube between 2 and 100. There are 4 perfect cubes in this range: 2^3=8, 3^3=27 and 4^3=64 but only one of them namely 64 is also a perfect square, so n=64=8^2=4^3. Sufficient.

So, my final tally is in. I applied to three b schools in total this season: INSEAD – admitted MIT Sloan – admitted Wharton – waitlisted and dinged No...
