Great videos sir, Can you please make a video which gives an overview of all the different strategies that are required to deal with different patterns of quant questions in the GRE.
I think the answer to the last question is SUB SAHARAN AFRICA even though it is not among the options because going by your explanation the ratio is approx 0.1 for that region. Or was there a reason for the ommission?
This is one of those situations in which you need to be very careful with the wording of the question. We're asked "For which of the following regions is the ratio...smallest." This means we're limited to looking at the regions mentioned in the answer choices and only those regions. We can (and should) ignore any other region mentioned in the table. There's no reason why Sub-Saharan Africa was left out. However, the fact that it is not one of the options means it cannot be the answer to this question, even though you're absolutely right that Sub-Saharan Africa has the lowest value for the ratio of all the regions in the table. I hope that helps!
question 4 wasn't the most efficient. we didnt need to calculate the percentage change. I know if i double 233M i get 466 thats a 100% change. If i add another 233M i get 699M. thats 200%. My answer is 220%. im enjoying this. thanks
You're correct that there are quicker ways of answering this question. I wanted to include the percentage change formula as it comes up a lot in GRE Data Interpretation questions. While the numbers in this question worked out and we could have used the formula you suggested to quickly reach the correct answer, the numbers won't alweys be so nice in other questions. If you're comfortable using the formula and using the estimation method you laid out, you're in a great position to take on these problems! Thank you for posting!
In Question 9, I feel the answer should be (B) 2/3 because they have asked how many times greater? It is 863 thousand greater which is (2/3)rds. of 1340.
This all comes down to the wording of the question. You're absolutely right that 863 is approximately 2/3 of 1340, but that's not what we're asked to find in this question. We have to put find the number we would multiply 1340 by to get 2203. It turns out that 1340 * (5/3) = 2233, so the number of secondary teachers in South-eastern Asia is approximately 1 2/3 times greater than the number of secondary teachers in Western Asia. This is why the answer to this question is (D). I hope that helps!
Omitting the 6 zero values from both sides make the calculations a lot easier

Love from Pakistan ✨💕 GRE is all about tricks ✨ Thank you for sharing
The only section on GRE I'm sure I will pass haha
In mean problems, allways
think the mean in relation with what
PERCENTAGE CHANGE: (p2-p1)/p
x down 20% percent in periode1 and up 20 percent in period2 (that come afeter p1) so x*(0.8)*(1.2)
