aki: It is 3*(2!*2!*3!)/5! = 3/5 and not 3!*2!*2!*3!/5! = 6/5
arjmen: I don't understand how you got these:
"Arrangements where both couples are together = 3!*2!*2!
Arrangements where only one couple is together = 2*(2!*2!*3!)"
Can you explain me please?
E.
Length of the square plot = sqrt(2401) = 49ft
So per row/column 8 trees can be planted.
Total number of trees will be 8*8 = 64.
Cost of one tree = $35
Cost of 64 trees = 2240
So total profit = $2240 - $896 = $1344
$1344 / $896 = x/100
x=150%
Today I received the final score report from ETS. :tup:
I was worried about the essay score because I didn't finish my essay. I didn't have time to complete the last paragraph/sentence and I din't have time to check for errors. Enough reasons to be worried. My structure score was 13-30 which I did't understand. As long as the righting counts for 1/2 of this section's score, it should be 13-28 or 15-30. 13-30 doesn't make any sense to me.
I am happy with my score. I needed at least 250 but I can leave with 273 :p
Good luck to everybody.
See you on GMAT section

I pick E.
If "not all good cooks are big eaters", it is certain that there are some cooks among all of them who are not big eaters.
A, B, C, D are possible even they may not be true.
Question2:
D) is out of scope because it is about the reserves already extracted (not in the ground)
E) Doesn't solve the paradox because the consumption can be smaller than the estimates but still higher than the production.
I pick E because there is only one which solve in part the paradox.
