You can also post your questions in the GRE sub-forum. We just started one a few weeks ago 😇 multiple-choice-select-one-or-more-gre-467/

You could post in the forum to get your answer. Otherwise teh answer would be 1. Since the arithmetic mean is 45k and not all are at 45k(range is 6k), none above and all above can be discarded directly. Next 1: surely one can be 3k above 45k and another 3k below 45k. Remaining three can be 45k. Possible…..finally 4: say each of these is x above 45k, so this has to be offset by the fifth one which is below 45k, that is 4x=y, but x+y=range=6000 or x=1200. Salaries are 46200,46200,46200,46200,40200.. But the salary is a multiple of 1000…not possible

We have two equations and three variables b, s and p: 50b+70s+100p=16000 and b+s+p=200. We require one more equation to find variables. Statement 1 gives b=s and statement 2 gives p=2b. Thus we will find answer in each case. Last statement tells us one of b, s or p is 100. Since average is 80 and closer to 100 as compared to 50, basic cannot be 100 but s and p can be 100: two cases 50,50,100 and 20,100,80. Thus, first two yes and third no

for this , you have to see the number of solutions for the equation , y=( x^2-x)(x-2). This eq can be rearranged as (x)(x-1)(x-2) by taking x common from x^2-x ......... now we can clearly see that equation y= (x)(x-1)(x-2) has three solutions 0,1,2 .. so graph that cuts x-axis at three points 0,1,2 will be the best representation of the function y option ’d’ will be the answer

When x is between 0 and 1, y is positive which is shown in graph D

There is a 10% chance of rain on a particular day. If it rains, there is a 10% chance _ that Jfon will go to school, out if it does not rain, he wil definitely go to school. What is the probability that Jon will go to school? How to solve this usinf table? Or can this not be solved using table? Please help

D. Why not C? Easy to test. Take a value beyond x = 2. Say x = 5. When x = 5, y = (5)(5-1)(5-2) = 5*4*3 = a +ve value. For choice C, the y value for an x=5 is negative. Choice D is correct. Do check out "wavy line method". The concept will be useful in this regard, I believe. Should be "wavy curve", I guess

The question can be solved using table too.

My attempt. Hope this is correct.

guys can anyone make a separate chat for GRE
