Hi,
3150 = 7 * 25 * 9 * 2.
To make this a perfect square, it has to be multiplied by a 7 and a 2.
Hence, the answer is 14. Hope this helps.
Thanks.

Nice! That's a good approach in solving this question. I took almost 2 mins to solve this question by pugging in each answer choice, and looking for which one gives a perfect square. This definitely makes a lot more sense! Thanks4GMAT_Mumbai wrote:Hi,

Being defeated is often only a temporary condition. Giving up is what makes it permanent.
so the number will be 3,15,014 = 7*7*25*9*44GMAT_Mumbai wrote:Hi,

Yeah, I got it right. I've found that for alot of the questions with squares in them require either the quadratic equation or factoring. Looking at this you know it's not going to be the quad eq, so start factoring (another hint is that the number is pretty large).
