For the last question - another logic can be as follows: 434-323 = 101, the increase 101 can only be justified if 11 fits (same odd-even reasoning) and 101-11 = 90, only divisible by 6. 101-33 = 68 (not divisible by any) 101-55 = 46 (same as 68) and 101 - 77 = 34 and lastly 101- 99. Potentially faster than the one u mentioned. Potentially faster way but it has its flaws

if y is deciduous then x can either be red oaks or japenese maples. as we no both of them are subsets of deciduous.

Hi Charles &Team, In Q3: We know Cedars is a subset of Conifers; and there are other varieties of conifers - spruces & pines. So in this case of subset vs superset which are not overlapping sets - isn't answer choice A&B valid too?

not really because you cannot determine the actual ratio. The question states to find the ratio. Even though the ratio of Cedars/conifers will be less than 1,we do not know the exact number of cedars hence we cannot determine the exact ratio.DC is the correct answer

Hey Charles! for the last Q why can't it be 11 & 10? It does fit the requirement, A > C Yesterday's Sale: 11*3 + 29*10 = 323 Today's Sale: 11*4 + 38*10 = 424 It also helps us find an answer which is the multiple of 5. As per the equation '5Qa = 125' Am I missing something here? Also, thank you and the rest of the team for such helpful and easy to understand videos on your channel!

For Q3, Cedar is the subset of Conifer meaning Cedar is less than Connifer. So, can the answer be X=A) Cedars ; Y=B) Conifers?

It would be great if you could post this question on forum. There is a greater chance that we will have some clarity by experts.

Hey Charles! Q3: The ratio of Conifers (32%) to Deciduous (~68%) would also be less than 1, right?

True. But the first condition is that we need to be able to determine the ratio and it is not possible in case of conifers to deciduous dueto deciduous percent being approximate.

It is likely to appear either as an experimental question or when you are doing really well and test is getting harder.

one in eight = is that 1:8 or 1/8? If 1:8 it means 1/9. How should we differentiate? Thanks

I don't understand why the answer of Q4 cannot be C & B. The increase in the population of the sea stars would result in a decline of phytoplankton and therefore the sea stars would start eating coral polys resulting in a decline of the coral reefs

What you said could make logical sense, but i think the focus is what is the cause and what is the effect resulting in the decline; and the increase in sea stars is a the main effect that results the decline. Now what is the cause for that increase in sea stars?.. increase in Phytoplankton helping them thrive

Why would a Bschool pick a candidate with 655 on focus edition vs 700 on old GMAT if they are trying to boost their average GMAT score. Very bizzare!!!!
