Reciprocal means a number that you multiple with a given number so that the product will be 1. For example, the reciprocal of 2 is 1/2, and the reciprocal of 1/5 is 5, and the reciprocal of -1/5 is -5.

since the square of n is less than 1/100, we know that in order to get even a smaller fraction, the denominator must increase. The number that this question talks about is -1/10 and if you square it, then you will get 1/100. so the denominator in -1/10, which is 10 must increase. The reciprocal of -1/10 is -10. So N must be less than -10, therefore A is our answer.

but i thought that x^2>4 -> x>2 or x<-2... does that logic not apply here?

yeap same logic applies here.

n^2<1/100

say 1/n =x

x^2 >100

x >10 or x<-10

answer is less than -10..
