It would be great if you explain the logic first and then go for the shortcut approach. No one, in their right mind, would want to mug up a formula for every new question that arises
Good point. Logic is necessary.
Absolutely right 👍

Exactly.
True...💯🤘🏾👍🏾
For the people who didn't understand the logic:
see the logic is nothing even close to complicated. Look at it like this:
for example: Q) 5 men does a certain work in 10 days. While 2 women does the same work in 30 days. Calculate the total work if 10 men and 15 women do the work together.
A) 5 men ---------> 10 days
2 women -------------> 30 days
so by basic middle school unitary method:
1 men -------------> 10 x 5
1 women --------------> 30 x 2
so 10 men ----------> (10 x 5) / 10
and 15 women -------------> (30x2) / 15
By the INVERSE LAW of time and work:
total work done by 10 men and 15 women will be:
[10 / (10 x 5)] + [15 / (30x2)] = (1/5) + (1/4) = 9/20.
Therefore total part of the work done by 10 men and 15 women is 9/20
And Hence total time taken = 20/9 = 2.22 days (answer)
THANK ME LATER ✨😌
Thank you
Thanks 😊
9/20
Tysm❤
This explains all these:
Men:
24 / 16 : 8 / x
Inverse proportion - more worker less time.
24 / x : 8 / 16
8x = 384
x = 384 / 8
x = 48 days for 8 men to complete.
Women:
16 / 24 : 6 / y
Inverse proportion
16 / y : 6 / 24
6y = 384
y = 384 / 6
y = 64 days for 6 women to complete.
Solve for time in days
( 1 / 48 + 1 / 64 ) t = 1
112 t / 3072 = 1
t = 3072 / 112
t = 27.42 days for 8 men and 6 women working together.
Exactly 😊 tysm it's helpful
Did the same way 😊
Thanks bro i understand by your comment not by this video thank you so much
@@jayakumarrock7506 exactly
Why we are inverse the proportion?
Can you please tell me
It help me alot.. thankyou...👍👍
Very good explanation 👌👍
Thank you sir,for giving idea
Bhai dil se bahut bahut dhanyawaad... ❤
Thank you for everything 🙂☺️
Thank you sir ji 🤗🤗

Bahut badiya sir apna trick bahut kam ayega
Thank you sir 👍
Thank you so much...
Excellent explanation
Wonderful Sir
Thanks sir 😀👏👏👍
awesome sir
There is no need to complete the solutiom by taking lcm and all. Just make it as simple as u can.
Good morning
How?
This place is not for the pepole with gold minded !
@@PraveenKumar-zs1gp yes
Excellent vedios
Sir mene UA-cam k ek s ek channel dkhe. Sbne basic s kraya but vo nhi kraya jo pucha jata h sbke common questions kra die .

thank you for intersting topic
TQ so much sir
Ur tricks were mind-blowing sir
Bahut Badya.......
The way you pronounce 'complete' word is incredible and funny af at the same time... 🤣😂
Superb
Thank you very much sir 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Excellent👍
First find total work i.e 384 by 16*24 or 24*16
Then divide total work by no. Of men or women i.e 48 and 64 find LCM for effiency then divide LCM by i e 192 by both efficiency 4+3=7. 192/7 = 27.428
Bhai thoda explain karke samjha skte ho
Darun sir
