We have 1/4A + 1/8 B = 1/2C and 1/4B = 1/4A thus A=B then Substitute

2(1/8B)=1/4A
Hence, A=B

Let A=8

A/4 + B/8
= 2+1
=3

C/2=3
C=6

A:C= 8:6
=4:3
C.

Very easy method to solve these type of questions:-
Let total work be 30 units [LCM(10,6)]
6m + 4w -> 10days -> 30 unit of work
that means they do 3 unit of work/day
Similarly 7m+4w -> 6days -> 30unit of work
that means they do 5 unit of work/day
Since only 1 m has increased we can safely say that 1m does 2 unit of work/day
so 3m can do 6unit/day.
so they will require 30unit/6unit/day -> 5days to finish the work

If 7 men + some women and completing it in 6 days then 3 men should definitely take more than 6 days.

I am giving my GMAT in 12 hours, Any tips?

stay calm, revise only the formulae and notes, not the questions, eat properly, get there on time but dont go in till you need to. It’s more of a mindset game at this point, you’ve already done all you can.

Oh and opt for a hoodie, they dont allow coats or jackets for some reason which is frustrating bec its cold!

Sometimes while I’m studying, I have the worst brain fog everything is blank. Does anyone have any strategies to overcome this? Any out of the box strategies?

@lin02. This depends on the cause of your brain fog. Are you eating correctly? If you try to study when you haven’t eaten properly, you will struggle with brain fog. Try eating a protein bar or something before. Is it due to a lack of sleep? Maybe study after a short nap. It could also be the time of day. Your brain will be more active at different times of the day. Try to figure out when you feel most mentally active and study then

hey everyone

if we won’t use calculator during the exam how are we supposed to calculate these for example?

Hey! Anyone got some advice for someone who is retaking the gmat in about a month with a current score of 515, and score goal between 535 to 600?

What material should I use, and how should I go about my study? What would be the optimal number of hours per day ?

this doesn’t check out once you go back and solve for w

Hello guys
My GMAT attempt is in the coming week and I’m facing two issues majorly:

1) the timing management for the quant section (and somewhat DI). I tend to panic for the last 6-7 questions.


2) word problem Typology of quant problems are difficult for me to solve.


Can someone suggest how should I go about addressing these please!
TIA

Hi All, I am facing issue while solving " Could be True" / "must be true" type questions in Quant, I try multiple combination of numbers but this takes a lot of time and if we miss any of the combination than the question gets wrong.

Could anyone help me with how to approach these type of questions.

Hey, here’s few things that helped me to get better :

1. If you are at the end of your prep, then trust me you have faced all those question, there’s nothing new that might grapple you during the last few minutes of exams.

2. Never turn away from approach - read, understand, map the solution and solve- this might take few more seconds but ask yourself - few seconds or a wrong answer?

3. As per the words problem, practice from the GMAT club practice questions. Go for understanding the question not for solving them first hand on. Once you have understood, then solve. Take your time and solve atleast 10 questions from 655+, . You will see the improvement yourself.

All the best for your exam!

Don’t panic, the answer is there and you can see it with calm mind. Long solution we go for easier questions.
Also most 655+ or 705+ question needs logic more than actual

It depends on what type of questions you are working over.

Mostly in algebra- with every must and could be true we have prior restraints given. For example a negative integer or a positive number or non negative integer.

In algebra the main point of focus after getting the answer is - is it a real number? Do we need integer? Do we need negative? Do we need non negative or non positive?

This will take practice but not more than 10 15 questions of 655+ questions and you will get hang of it.

If it’s about advanced topic - once again understand the logic, write down the given jnfo, picture the scenario and when the answer comes - align it with what the question has asked.

Practicing - doing the checking over and over again that it becomes ingrained.

Read, understand, make a pathway, write what’s given and solve.
