When i started my GMAT prep a month ago i was acing the Quant section with 80 score and just to focus on weaker section i.e DI i started attempting Quant as last section and started screwing up heavily and lost all confidence in Quant sometimes later i was not even able to solve medium questions. Today i started watching this playlist and just from 1 video i got some confidence back and started realizing where i was getting wrong. Thanks GMAT club.

Was going to go to bed and instead, I figured I’d spend the extra hour and watch this. So happy I did, this was awesome. Thank you Sir!

Scones and Croissants question. Possible combination of Scones and croissants that can be produced in an hour are ( 6C, 0S) (4C, 1S) (2C 2S) (0C, 3S). As more scones need to be produced than croissants we can assign all the workers to do scones first. For 1440 scones, that means 1440/3 hours = 480 hours or 480/8 people or 60 people. Remaining workers can focus on maximum croissant production i.e. 6 per hour or 48 per shift. for 1200 croissants, 1200/48 or 25 shifts or 25 people. Together 85.

I was able to get the last question using a different method that didn't rely on recognizing the pattern of fractions cancelling.

I noticed the numerator is always 1 (fraction is negative). We know there are 20 numbers so the sum must be -20. There was only one option in the answers where this could be true. Wouldn't work if the answer selection was more difficult.

Hey- the croissant question. The question said 1 baker can make 1 pastry in 10 minutes and the other pastry in 20 minutes. Does that phrasing not imply that they are doing both of those things simultaneously? I didnt add them for that reason

Please do this for me 🙏

Kate likes to walk down moving escalators and she takes one step at a time. When she walks down at a rate of 2 steps per second, she reaches the bottom from the top after 18 steps. When she is exhausted, she will walk down at a rate of 1 step per second and she will reach the bottom from the top after 12 steps. Find the time- taken for her to reach the bottom from the top if she just stands on the escalator.

In croissant question. How do u come up to dividing the total hour sum by 480?

[almersad]

still not sure about the answer in the vid for question 5 because the question said "each baker can make one croissant every 10 minutes AND (NOT OR) one scone for every 20 minutes", so I assume that every bakers produce both croissant and scone but in different producing time. Please enlighten me, thanks

I am a bit confused by the answer to question 5. It says each baker makes 1 croissant in 10 minutes and 1 scone in 20 minutes, should it not be the case that the same baker can make both simultaneously? Which means we would only need 60 bakers?
