The argument states that female population between 20 and 21 has increased over the years. If there is an increase in the proportion of the male (between 20 and 21) enrollment as well...then the argument would fall apart.

for DS questions - square root

Lets say the question says...

whats the value of x?

1. sq root(x) = x-2

oops...sorry...POE - process of elimination (am pretty much doing an either or)

yes...for the first choice applying Pythagoras theorem a^2 + a^2 = b^2...gives us sq root of (64 + 64) = 8(sq root of 2) which is not what's expected - 16(sq root of 2). Hence proceed to 2

IMO C

is it B?

Assumption negation - neither...nor

If an answer choice contains - neither x nor y learned about something

how do we negate it?

Both x and y learned about something

or

either x or y learned about something

Thanks
