Thanks. I dont know why but to me it appeared that 0-7 so range should be 7. Anyway, thanks. 6 is what the right answer appears to be on the GMATPrep software.

Thank you for the response. Where can I find the percentile mapping to the score, that you have mentioned?I mean, how did you map 23 correct on Quants to 51 percentile and 25 correct on Verbal to 92 percentile?

Well, it does give a clue, but I am unable to accept 'are' with 'land' even it it is thousands of acre. According to me, land should go with singular so the right answer should be C. However, as per the source, B is indeed the right answer.

The answer is 3a. You just have to resolve the parenthesis -
b-[b-(b-a)-{b-(b+(b-a))+3a}]
=b-[b-b+a -{b-(b+b-a)+3a}]
=b-[a-{b-(2b-a)+3a}]
=b-[a-{b-2b+a+3a}]
=b-[a-{-b+4a}]
=b-[a+b-4a]
=b-[b-3a]
=b-b+3a
=3a
