@gmatclub Please continue to do more such videos it is very helpful🤞🏻Thank you!

Thanks for this!

This quant series was really great and helpful ! Thank you @gmatclub and Charles !! Request if you could share more session within this series on topics- number properties, probability, P&C. Also, wanted to understand how many questions can we expect in Quant section from Mixture word problem ?

thank you very much

Great videos, Charles make more videos on Gmat Focus as you are the TOP G

Hey Charles! Your humble teaching style never fails to amuse me. Thank you for appreciating admission of mistakes/confusions/questions. A sincere request to release more Starter Kit videos for topics such as PnC and Coordinate Geometry. Would like special emphasis on attempting questions from those topics in the most efficient way possible (same as the current starter kit).

Super helpful video, thanks! Do you have a video on combinations, permutations, etc.? It seems like there is at least one question on that every time.

Love your quant VDOs! Can you also make vdo for harder levels of Quant questions, please?

I really like Charles's teaching style. Thank you so much for creating the Maths Starter Kit. Can we expect more such videos in the future on other topics like Probability, P& C, and Sequences & Functions? Thank you!

Since number properties also forms a major portion of quant questions, could we get a starter kit video on this topic also pls?

Q4, DS question. 10% tax means, price is 70 and tax is 7. If the overall price is to stay the same at 77, there are two possible options, either p>70 and t

Hey Charles! Just completed the entire GMAT Focus Math Starter series today. Thanks for the invaluable questions. I have a slight issue on the last bakery question. Statements 1 & 2 individually are easy to eliminate leaving with choices C or E. How does the % change for February determining what % change occurred for other months? The question no where states the % of muffins sold for bakery B cannot be less than 10% for other months and % of muffins sold for bakery A cannot be more than 10% for other months? How are we concluding on the basis of just one single month? Please let me know what I am failing to understand.

Q3, question about durian and mango. easier way to answer this is to look at the ratios that were give. Initially 3:8 and later 1:3. So initial Durian total must be a multiple of 8. Otherwise you get fractional Durians. That rules out C and E. (3,8) (9,24), (33,88) becomes the possible set. Taking 3 mangoes out and adding durian means, we are left with the last set (30,90) that meets the ratio of 1:3. Answer is D/88

In Q3, I solved it using 2 variables i.e, X for mangoes and y for durian which gave me 2 equation to solve and get answer 88. was this method incorrect?

Shouldn't Q4 be E ? .. because B says pre tax price is less than 70 .. where's the equation we get is pre tax price greater than 70 ..

Q3. How is 3x-3/8x+2, one-third?

Q5, (1) is insufficient because you are just given % and not absolute value. (2) tells us the value in Feb but nothing about the rest of the year. So A, B, D are out. If we combine the data, we get the following, Bakery A produced less than 10% of their yearly total in Feb and the Feb production was greater than 3500. Thus at least 10% of the total must be 3500 or total production must be at least 35,000. Similarly Bakery B produced more than 10% of their yearly total in Feb and Feb production was less that 3500. So 10% of yearly production couldn't be more than 3500 or yearly production couldn't have been more than 35,000. Thus C. Another way to look at the combined data. For Bakery A 3500 < Feb Production < 10% of total or 35000 < 10* Feb Production < x. For Bakery B 10% of total< Feb production< 3500, Total < 10* Feb production < 35000 Thus Bakery B is less than 35,000 and Bakery is greater than 35,000.
