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 ✨😌
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
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 . Apne vo questions lie h jo puche jate h🙏 I m grateful to uh🙏 thanks a lot 🙏
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.
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
24 men ---> 1/16 part of job/day. 16 women ----> 1/24 part of job/day 8 men ---> 1/48 part of job/day 6 women ---> 1/64 part of job in a day 1/48 + 1/64 = 1/n n = 192/7 days.
Tell me answer this question sir please 400 व्यक्ति किसी काम को 10 दिन में पूरा करते हैं 32 व्यक्तियों ने काम शुरू किया यदि हर 2 दिन बाद व्यक्तियों की संख्या 2 गुनी हो जाये तो बताये कार्य कुल कितने दिनों में समाप्त हो जायेगा
Three Serviceman come to check a telephone booth every 6,7,&14 days respectively. If they all happened together today, after how many days will they together come to this booth
Arnab is twice as fast as Bhanu, and Bhanu is one-third as fast as Chandu. If together they can complete work in 30 days, in how many days can Arnab, Bhanu and Chandu do the work respectively? How to solve these question by trick plz make video on it
@itsaaron6423 Hi, if they're completing the work together in 30 days then how can B complete it alone in 30 days? It's not feasible. They'll take a lot of time doing it alone. A: 50, B: 100, C: 300. This should be the ans.
*Ans of Q2):* In 1 day, 15 men and 6 women can do 15/(10*10) + 6/(12*10) = 15/100 + 6/120 = 3/20 + 1/20 = 4/20 = 1/5 work 15 men and 6 women will complete the work in *5 days.*
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)

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

Why we are inverse the proportion?

There is no need to complete the solutiom by taking lcm and all. Just make it as simple as u can.

Bhai thoda explain karke samjha skte ho
Excellent explanation
24 men ---> 1/16 part of job/day.
16 women ----> 1/24 part of job/day
8 men ---> 1/48 part of job/day
6 women ---> 1/64 part of job in a day
1/48 + 1/64 = 1/n
n = 192/7 days.
I also approached this question like this.

Tks sir for this nice maths but please we need the logic for the formula before solving.
Sol if 36 workers can do a piece of work in 25 days,in how long many days will 20 workers do it.
36*25=days*20( as both doing same work)
Final days =900/20=45 days

Nice
1 &2d qns are similar but solving is different plzzz give me the correct logic to do the prblms
checkout ua-cam.com/video/prs4FCwOmw8/v-deo.html for solving based on logic
*Ans of Q2):*
In 1 day, 15 men and 6 women can do
15/(10*10) + 6/(12*10)
= 15/100 + 6/120
= 3/20 + 1/20
= 4/20
= 1/5 work
15 men and 6 women will complete the work in *5 days.*

good it's very easy method
24 X 16 = 384
