So number 45 is incorrect. The same logic that was used to cancel out 11 = 3+8, also cancels out 3+5=8, therefore the correct answer is II or A, because 8<8+3.
for question 46 see what numbers u can put so that result remains less than 25 and there are 4 possibilities or integers that can make it possible its 0,1, 2 , 3 u cant go above it as it will make the product greater than 25.
42% of 100 + 42% of 100+ 42% of 100 = 42+42+42=126
Add 114+126= 240 (# of seeds germinated total)
500 is the total # of seeds so
240/500 ..at first glance you can tell the answer is somewhere between 40 and 49%..so if you don't want to do the math..look at possible answer choices...if they are close then do the divison.
For problem 45, Sal's explanation can also be applied to a triangle with 3, 8 and 5 as 3+5 = 8. The answer is (A) II only. This is a very easy mistake you can make in GMAT with its time constraint so be careful.

Problem 45... Choice I: 3+5=8 can't be a triangle the same way choice III: 8+3=11 can't be a triangle. Weren't saved by the choices this time. :(
thx for the video. you rule!

#44 Could be solved much simpler
Plot 1 57% of 200 could be looked at as:
57% of 100 + 57% of 100 = 57+57 = 114
Plot 2 42% of 300 could be looked at as:
42% of 100 + 42% of 100+ 42% of 100 = 42+42+42=126
Add 114+126= 240 (# of seeds germinated total)
500 is the total # of seeds so

#45 is II only. I is eliminated by the same logic as III was.
