A+B+C. Can do in 30 days A+,C=2B so it is same as 3B can do it in 30 days. B can do it in 90 days A+B=3C so 4 C can do it in 30 days. and C can do it in 120 days. Now if we take total work as LCM of 30,90 ,120 = 360 units then we have efficiency of B 4 and C 3 and A+B+C 12 so A efficiency is 5 A can do the work alone in 72 days.(360/5).
Thank you!! Start - 3:39 Concept : 46:58 - My wrong logic Imp Qs : 8:47 (How to form individual ratios here in these type Qs ), 26:36 - taking LCM again. 36:33 (Equating work on both sides was key here, Note-TE is hard, )
Your videos are top notch. I was so weak at maths and being from a commerce background but your videos are helping me for preparing Mba entrance exams specially CAT. Thank you for uploading these sessions.
sir why can't we use lcm approach in the last ques? [5men and 8 women can complete a piece of work in 30 days......] just like we used in 7 Indian and 4 Chinese wala ques?
In the previous 5 sessions, we learned how to not use a variable while solving these questions, which is absolutely fantastic if you ask me. Now, in practice sessions, sir uses variables to solve these questions. Phew, great teacher, but...
12:52 Que 2: there was literally no need to even write anything to solve it. And also I feel the way you explained was too stretched version. It's simple: 10 men= 20 boys 1 man= 2 boys So 8 men+ 4 boys means= 10 men And that's what already given I.e. 260 You can understand this que orally only👍
Amazing content sir, your efforts are really worth alot more than just verbal appreciation. Can't we use the LCM approach to solve the last question?? 40:46
10x20/260 = 8x20/w2 ( for men ) which will give answer of 208 tables 20x20/260 = 4x20/w2 ( for boy) Which will give answer of 52 tables. 208 + 52 = 260 tables.
Last que: LCM APPROACH: Total work= Lcm of 30 & 10= 30 5M makes 30 units in 30 days means 1 man is making 0.2 units per day i.e. 5 men are making 1 unit per day 60 Men× 0.2= 12 units per day 30/12 = 2.5 days But, to apply this we should know that women's efficiency is zero so that we consider men only. So Lcm approach is incomplete here
17:9 wala question mein ,sir ke answer galat he please check sir ap bhul gaye ki pehle mein 10 men v tu the 10men and 20 boys = 8 men and 4 boys How is it possible I think the answer is 130 tables please check Thank you sir Respect❤️.

A+B+C. Can do in 30 days
A+,C=2B so it is same as 3B can do it in 30 days.
B can do it in 90 days
A+B=3C so 4 C can do it in 30 days. and C can do it in 120 days.
Now if we take total work as LCM
of 30,90 ,120 = 360 units then we
have efficiency of B 4 and C 3 and A+B+C 12 so A efficiency is 5
A can do the work alone in 72 days.(360/5).

RESPECT FOR YOU SIR THIS TYPE OF CONTENT IS NOT POSSIBLE BY ANY HIGHLY PAID TUTION/COACHING CLASSES.
Your videos are top notch.

U r love sir amazing... I m from Non-enginer you clear my all basic in just 5 hour Amazing👍
Sir, tank wala question bhi kara do naa.... Tank fill topic...
Sir the way you teach helps me a lot!!
Quants was never so understandable before
Thanks a lot!!

Thank you for providing these sessions , It's so helful.
THANKYOU SO MUCH SIR, YOU AND RAVI PRAKASH SIR WILL BE THE REASON IF I CRACK ANY MANAGEMENT EXAMS THIS YEAR😇
He is the best ❤️❤️I wish mai ense kabhi life me milu
Sir hats off for providing these videos ❤️🫶🏻❤️🫶🏻
Sir your all concept is very clear
12:52 Que 2: there was literally no need to even write anything to solve it. And also I feel the way you explained was too stretched version.
It's simple: 10 men= 20 boys
1 man= 2 boys
So 8 men+ 4 boys means= 10 men
And that's what already given I.e. 260
You can understand this que orally only👍
Thank you so much sir 🙏 bohot clearly samjhate ho aap mujhe bohot achhese se smjh me aaya time and work ❤u r best sir❤😊❤🙏🙏🙏
Another class with so much details
Really appreciable... thank you sir ❤
Thank you so much for amazing series
Amazing session sir thank you so much😊👏👏👏👏👏🙏🙏👍👍👍
Excellent session sir. Superb clarity❤
ULTIMATE U, ULTIMATE UR TEACHING 🙏👌
Underrated Udit Sir
This series is best
How to use mdh in that 10 men or 20 boys question sir? Did not understand.
Sir aap great ho 🌸
Thank you so much sir.❤❤
Sir bahut mja as gya
sir isi playlist mein pipes and cisterns ki videos bhi daldo plz
Sir how can you equate 75 and 100 work, shouldn't we make both the work same and then equate?
Thank youuuuu sir. This is so helpful
❤ amazing teaching style.
SIR AP CAT LEVEL QUESITON POST KIJIYE , TIME AND WORK KA ABTAK KA PLAYLIST ME 20% QUESTION HI SOCHNE LAYEK THA
Yes series is great
Amazing content sir, your efforts are really worth alot more than just verbal appreciation.
Can't we use the LCM approach to solve the last question?? 40:46
Thanks a lot Sir ....
17:40 how this question be solved with mdh approach?
10x20/260 = 8x20/w2 ( for men ) which will give answer of 208 tables
20x20/260 = 4x20/w2 ( for boy)
Which will give answer of 52 tables.
208 + 52 = 260 tables.
mza aara h sir
th-cam.com/video/XeL8qeLcMaI/w-d-xo.html
Last que: LCM APPROACH:
Total work= Lcm of 30 & 10= 30
5M makes 30 units in 30 days means 1 man is making 0.2 units per day i.e. 5 men are making 1 unit per day
60 Men× 0.2= 12 units per day
30/12 = 2.5 days
But, to apply this we should know that women's efficiency is zero so that we consider men only. So Lcm approach is incomplete here
27:49 4th que: is there any other way to solve this question?
lovely👍
Brilliant Sir 👌👌👌👌
THANKU SIR
sir man women children waale toh karayehi nhi aapne
