yes surely, 2 questions can get the score up by a couple of points easily. In DI, it is more of silly mistakes, not understanding what is required

Yeah. At least in a 2-3 questions always.
I’m trying to reduce those errors.

Hi @chetan2u, just wanted to check if you had a chance to put up the DI review/ official guide questions. Just the non-DS questions would be of great help as well! :)

We are looking for whether these 5 party A leaders also had approval ratings greater than 50% from remaining party members, that is party B and party C. If you look at those % columns for these five leaders, Ist, 4th, 6th, 8th and 10th, none have all columns greater than 50% from all parties. Rather there is only one leader 7th, who fits in this category but is not from party A. What is the OA?

5 and none

for any leader, 50% of each of three parties should give a thumbs up. so each column should be greater than 50%

It should be A. You will get k from the equilibrium point by putting in demand curve, K=PQ = 10*5=50. The supply curve will give you an equation in a and b. Another equation in a and b will give values of the two variables. Statement ! does exactly that thing

The first time 2 switched with 4 so the sequence was 1 4 3 2 5 6 7 8. The next year 2 switched with 6 so the sequence became 1 4 3 5 2 6 7 8.

Sorry the next switch is with 5 not 6. the answer should be 4 and 5.

The clue that you have is that the apartment 2 is between 5 and 6. But they are consecutive, so there has to be an exchange of either 5 or 6 in one of the exchange. Let us say it is 5. If 5 is exchanged in first then the place of 5 would be far off 1,5,3,4,2,6,7,8, so 5 would have got changed in second shift. This means 2 was at 4 before second shift(1,_,3,2,5,6,7,8), meaning the first shift was with 4. (1,4,3,2,5,6,7,8)=>(1,4,3,5,2,6,7,8). But there could have a second case too. (1,7,3,4,5,6,2,8)=> (1,7,3,4,5,2,6,8), that is 7 & 6, BUT 7 is not there in the option.

Re: Data Insights Question of the Day [#permalink] New post   08 Apr 2024, 03:19
If y < x, is x^2 < y^2 ? (1) y > 0 (2) x > 0

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements (1) and (2) TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.

can someone please explain/ teach me how to solve this question

i guess the answer is Statements (1) and (2) TOGETHER are NOT sufficient

isnt it?

should be A - as under all instances it will give answer as No. With statement 2 - there will be 2 cases which will give either Y or N hence NS

This question is discussed here:

The OA is A.

P.S. Please note that pure algebraic questions like the above are no longer included in the syllabus of the new GMAT Focus exam format.

lets assume values of x and y . x =2 , y =1 (as it is given y<x), hence x^2 > y^2 which means No. IF we try statement B -y can be either negative or positive and square of that can be either smaller or greater than x^2, hence not suff to answer
