IMO D

(1/5)^m * (1/4)18 = 1/2(10)^35

5^-m * 2^-36 = 1/2(2*5)^35
5^-m * 2^-36 = 1/2(2^35 * 5*35)
5^-m * 2^-36 = 1/(2^36 * 5^35)
5^-m * 2^-36 = 2^-36 * 5^-35

equate LHS = RHS

so -m = -35

therefore m = 35

I hope I am clear

Priya this is not the right place to post this query,
but still i'll answer your question........ your academic profile seems to be very good...but the B schools looks at your overall profile rather than looking at a single faactor such as GMAT or acads....I would suggest you appear for GMAT as I think one should eliminate this barrier as soon as possible...and then concentrate on building your profile, I mean in the terms of quality and not quantity i.e the number of years of your work ex.

It's clear, thanks! I solved it myself in the exact same way.
I confirm that the OA is 35.
