Problem Solving (PS) | Re: How many bits of computer memory will be required to store the integer

Hellocarcass , may be I am wrong. however, however for me this problem looks exactly similar to the problem in GMAT PLUS where the question is:


\({-}\sqrt{810,000} - \sqrt{810,000}\)
Followed by this option

(A) 25
(B) 24
(C) 17
(D) 13
(E) 12

Answer for the above question is D - 13 and solution is as per below:

\(-900 - 900 = -1800\)
As there are three unique digits and each units require 4 bits answer will be\(= 4*3 + 1 = 12+1 = 13\)
