Quant Question of the Day Chat

Harsh truth of life I learnt. Even though people respond to others, just dont expect them to respond to you. Understand that your queries are valid. But frankly, even on my end, I never expect Bunuel to respond. Bunuel of all people who is prolly the most busiest here needs a lax. Also cause Pooja, we both are super active people on this site. And honestly, it took me a lot of scrolling to find the Question you posted earlier.
As someone who have historically moderated chat sites during my teen years (I’ve been on chat sites since I was 8 yo with my parents knowledge), its the active people that are the hardest to keep track with.
If Bunuel or any moderators dont respond to me, I know its prolly cause I post too much it easily gets overlooked.
Not denying your feelings. You’re valid. But Bunuel surely have a valid reason.

Malar95,I respect your feelings towards Bunuel or any of the club members. I do understand they might get busy at times. But this is not for the first time had happend to me that he didn’t respond to me. Many times he had ignored me general or maths queries. Hope you can understand that how does one feels when their queries get ignored. This club is a community where not only the club members provide their volunteer services even students volunteer. So, thank you my friend for taking your time to respond to me and for your understanding too. Your concern towards the queries is always appreciated.

Thanks for understanding my POV.

Write the equation of a line that is perpendicular to y=−12x+4 and goes through point (0,6)?

If I’m not wrong this is coordinate geometry.

Is it a part of focus edition?

I checked GMAT’s Quant book, the official one and unfortunately Coordinate Geometry is part of the Syllabus. I for one, have yet to practice a Q from it except for my basic HS knowledge.

Kill me.


Not literally.

But also, I’ve had similar thoughts/queries too

12y = x + 72

is it right?

No

A perpendicular line has a negative reciprocal slope to the given line.

The given line, y=−12x+4, has a slope of −12 , as m is the slope in the standard form equation (y=mx+b).

Slope of perpendicular line: m=2

Point: (0,6)

Using the point slope formula, we can solve for the equation:

y−y1=m(x−x1)

y−6=2(x−0)

y−6=2x

y=2x+6

Yeah but product of slopes of perpendicular lines is m1.m2 = -1

so m1 is -1/12

hence m2 should be 12

I am not sure how you got m as 2

Just a question, I have filled the gmat focus edition form, planning to apply this year itself, is it fine?

Q: How many positive integers less than 500 have a remainder of 1 when divided by 7 and a remainder of 2 when divided by 3?
Options:
20
21
24
26
72

For N<500, let N= dx+r, The divisor d would be the least common multiple of the two divisors 7 and 3, hence d=21 and the remainder r would be the first common integer in the two patterns, hence r=8 So, the general formula based on both pieces of information is total= 21x+8 So there are 24 numbers less than 500 that gives a remainder 8 when divided by 21.

This beautiful concept has been clearly explained by Bunel in this 700 level beautiful question: https://gmatclub.com/gmat-practice-test ... 17566.html

You can find detailed discussion of this question here: https://gmatclub.com/forum/how-many-pos ... 21279.html Hope it helps.

Thank you. That question is discussed here: https://gmatclub.com/forum/m23-184357.html Hope it helps.

A big salute to all the those who have framed all these beautiful questions in GMAT CLUB Tests. All are super tricky and looks very difficult to solve, until Bunel shows up with 2 step simple solution for that complex looking problem A tight slap on our face

Thank you for the shout-out! I'm really glad to hear that the questions and solutions are proving useful. I put a lot of time and effort to create them, so your feedback is truly appreciated. Happy studying!
