Please explain the following.....

Aleehsgonji · Answer

Given square of the number is less than 1/100
then the number should be less than 1/10.
The numbers between 0 and 1/10 satisfy this condition.
As numbers are on the left side of the number line, the numbers should be between 0 and -1/10

look IMO A,

the number here shuld be -1/11 , - 1/12, -1/13 and so on because square of these numbers would give less than 1/ 100 i.e 1/121 or 1/144 so on..... so reciprocal of these no would give -11,-12,-13 and so on

thus option A is correct

Please post your questions as an image rather than Word attachments - it is easier to read and more efficient (don't have to download files).

You can do it by saving them into the MS Paint or equivalent Mac application and then uploading as an attachment in the same manner as Word, except images will actually render.

Give it a try.

Good explanation bb!

gmate2010 · Answer

n^2 < 1/100 ( n is on left of 0; this means n is negative , we can eliminate D and E choices as 1/n can not be positive)

=> -1/10 < n < 1/10

Taking inverse always reverses the equality sign

=> -10 > 1/n > 10

But n is negative, so 1/n can not be greater than 10

Hence, 1/n < -10

Hence, answer is A..
