Why is it so expensive? I really enjoyed these 40 problems and the tips you give, but I can't afford to pay 100 USD for the rest. Too bad.

[@td_2023]

@The Organic Chemistry Tutor, could you create a course on GMAT, especially, the quantitative section? Going over Data Sufficiency and problem-solving questions starting from the basics? I bet a lot of people will pay for that including myself. Especially for those who need to take the GMAT for their MBAs. Please let me know if you will, so I can be on the lookout.

[@gradgoals3011]

I was thinking that in the first place, but the answer is actually 10.5 The answer would be 13.5 if the question was, "how many cans are required to finish THE ENTIRE house?" Since the question asked, "how many cans of paint are required to finish THE REST of the house?" , we need to subtract what we already have. I hope it helps.

I believe #32 1:20:43 is incorrect. Even tho x is larger for Column A the 1 in the numerator actually makes Column B greater. For example, 1/100 is SMALLER than 1/10 so the answer is B not A

On problems like #5, I plug in each answer choice to see what results in 15- which I think is much easier and quicker...

[@Sam-wu5ry]

q10 the answer is d because in x= 1/2 x^2= 1/4 and 7x+4 = 15/2 in this case column b is greater and since there is a case where a is greater than b and there is a case where b is greater than a, the correct answers is d because it can not be explicitly determined because of contradiction.

is this still relevant for the GRE in 2021? Thanks for this! Great teaching skills

[@andreagaribay4597]

[@rohithraj5452]

Being a grade 10 student I was able to solve this to a good extent

[@beatrizyepes4491]

In question 32, I believe the answer is the contrary of what you said. If you take the first number you tried for the fraction, you get 1/x^2= 1/100 and 1/x=1/10. In this way, 1/100 is actually smaller than 1/10

[@aashivpatel6031]

X is between 0 and 1, so if x = 0.1, x^2 = 0.01 and 1/x^2 = 1/0.01 = 100. Therefore, 1/x^2 is greater than 1/x as long as 0

I think the answer to question no.13 is option E) 24. Since the total number of marbles is 36. If 12 is the number of blue marbles, then the number of red marbles is 36-12=24

[@RiRiRachel89]

Gabriella Mawlong There are 30 marbles

[@gabriellamawlong1936]

I was thinking that since there are 12 blue marbles. So out of the 30 marbles 18 will be red marbles and since 6 more red marbles are added. So 18+6=24 red marbles. This is what i thought. Please do correct me if I'm wrong.

[@RiRiRachel89]

Gabriella Mawlong It’s telling you that within the jar of 30 marbles, there are 18 red & 12 blue. There were no marbles added. “6 more” is a way of say 12 (blue marbles) +6=18 (red marbles)
