I think the answer is B. - Pick a number of X --> x= 40, john and mary got 40 each in advance - Calculate hourly rate --> john works 10 hrs, so hrly rate is 40/10 = $4 hr mary works 8 hrs (i.e. 2 hrs less than John), so hrly rate is 40/8 = $5 hr - Mary has to give John $10 (y) in order for him to re...

With just 10 days left, you really only have 3 days to improve your weaknesses and then the 7 days to keep working on your strengths. I would suggest reading a prep book that covers CR by section and doing problems relating to that section. Try to understand why you're getting the questions wrong. C...

The answer is E.

First solve for x (2x and 3x form a line which is 190 degrees)
2x + 3x = 180
5x = 180
x = 36

Now solve for y (angles 2x and y +30 are equal)
2x = y + 30
2 (36) = y + 30
72 = y + 30
y = 42

the method i used to solve it was to add the following 1/99 (#2) 1/98 (#6, also decreasing the pool to 98 since 2 is no longer there) 1/97 (#67, also decreasing the pool to 98 since 2 & 6 are no longer there) 1/96 (#72, also decreasing the pool to 98 since 2,6, & 67 are no longer there) = 1/24

This question is testing the verb tense and idiom. Verb Tense - You use the past pretense because the sentence is structured like "then and now." first half of the sentence describes how the ozone appeared in the past and latter half of the sentence describes the ozone now. Idiom - As for ...

I think its C.

so my best advice on these questions TT is to take each sentence one at a time and compare it to the answer choices.
