A+B+C = 2 * 36 / (4 + 3 + 2) = 8 days
*Note:* LCM of 9, 12, 18 is 36.
A = 12 * 8 / (12 - 8) = 24 days
B = 18 * 8 / (18 - 8) = 72 / 5 = 14⅖ days
C = 9 * 8 / (9 - 8) = 72 days
Why 2 is Multiple with 36 pls tell me

That's formula...

Thank you
Why did you write 4+3+2? Where they come from??
I want profit and loss tricks....if possible then share also
Sir please solve it- A and B together can complete a work in 3 days. They start together. But, after 2 days, B left the work . If the work is completed after 2 more days, B alone could do the work in ?
6 dayz
Remaining work 1 - 2/3 = 1/3.
1/3 work is done by A in 2 days.
A can complete the work in 6 days.
*B can complete the work in*
6 * 3 / (6 - 3) = *6 days*
Nice sir I'm from Nepal
Lcm of 9,12,18=36
((A+B)+(B+C)+(C+A) ) =36/9
2(A+B+C)=4
A+B+C= 8 days
This is not easy trick because calculation is very difficult,first besic is easy and short for calculation in exam.
I think you did not understand this.... This is one of the easiest trick available in TH-cam. I watched so many videos and channels but this one is so cool.

days and abc do 6 day then ac when do the work ? Plz taratari reply karia
A+B can do the work in 6 days.
A+B+C can do the work in 6 days.
Means *C is dummy person* (not doing any work).
B+C can do the work in 12 days.
Means B can do the work in 12 days.
A can do the work in 12 * 6 / (12 - 6) = 12 days.
*A+C can do the work in 12 days.*
Woww nice explanation.......all cleared.... Thank u so much
Sir apki voice bhut kmm arahe hai thoda loudly bola kru plzz
5 men can do a work in 20 days, 8 women can do a work in 25 days and 10 boys can do a work in 30 days. in how many days does 2 men, 6women and 5boys complete the work???
solve it asap using tricks
Babu Mishra 15 Ans Hai
15 days
20 days
14 days
Theirs works are equal but efficiencies are not equal.
5m * 20 = 8w * 25 = 5b * 30
= (2m+6w+5b) * x
100m = 200w
w = m/2
100m = 300b
b = m/3
100m = (2m+6w+5b) * x
100m = (2m + 6(m/2) + 5(m/3)) * x
100m = (20m/3) * x
x = 100m * (3/20m) = 15
*Ans = 15 days*
Plzzzz kya ish video ke 2nd ques ko ek din ka kaam jese nikalte or phir separate kese nikalenge koi bta sakta h yaha plzzzzzzzzzzzzZzzzzzzzz
Sir add a videos on partnership chapter
1st question lo A+B+C= 1/4×1/2 how?,,???
thank you so much sir....
6 boys and 8 women finish a job in 6 days and 14 boys and 10 women do the same job in 4 days. In how many days working together 1 boy and 1 woman can finish the work? kindly solve this question too. thanks
Muhammad Ahmad ans will be 15.83 days
23days
(6b + 8w) * 6 = (14b + 10w) * 4
= (b + w) * x
(6b + 8w) * 6 = (14b + 10w) * 4
36b + 48w = 56b + 40w
8w = 20b
(6b + 8w) * 6 = (b + w) * x
Multiply by 8 on both side
(6b + 8w) * 6 * 8 = (b + w) * x * 8
(6b + 8w) * 48 = (8b + 8w) * x
(6b + 20b) * 48 = (8b + 20b) * x
26b * 48 = 28b * x
x = (26b * 48) / 28b
= 312 / 7
= 44 4⁄7 days
*Ans: 44 4⁄7 days*
ans must be between 36 to 40 below.
Good tricks
Pls see video for magic of 9
Sir increase sound
Yes you are right
In a exam durba score 75%. In a other exam he score 20out of 25 then his total score is 78%.what is the full marks of first exam?

This is not short cut brother.
Ya... Time consuming...😶
How did you got 4+3+2 please explain..
Siri Prince in this place i also confuse,,,
Inko pata ha 4+3+2 kaha sey ayaa
Par humko samjhane ki zaroorat nahi laga..
Asey calayengey class
4x2 =8
3x3=9
9x2=18
Here.. LCM is 36...here you have to compulsory multiply the numerator with 36 and divide by denominator nos..heres how.. 1×36÷9=4; 1×36÷12=3; 1×36÷18=2.. I hope you are clear with that..he used shortcut method
1/9 + 1/12 + 1/18 = ?
LCM of 9, 12, 18 is 36
Numerator is 1 and denominator is 9 of 1/9
Now we have to divide LCM by denominator and multiply it by numerator.
*We got* (36/9) * 1 = *4*
Similarly numerator is 1 and denominator is 12 of 1/12.
*We got* (36/12) * 1 = *3*
Similarly numerator is 1 and denominator is 18 of 1/18.
*We got* (36/18) * 1 = *2*
1/9 + 1/12 + 1/18 = (4 + 3 + 2) / 36 = 1/4
(A+B) + (B+C) + (A+C) 1day work = 1/4
2A + 2B + 2C 1day work = 1/4
A + B + C 2 day work = 1/4
A + B + C 1 day work = 1/8
*A + B + C can complete the work in 8 days*
How come minus????
Tumhara trick use korenge toh 1hour mein 1answr hoga
c ca n do work in 12 days i think
Sound boht km h
Thank you very much sir
Awaz Boht kam aa rahi h
Raju can do a piece of work in 10 days, Vicky in 12 days and Tinku in 15 days. They all start the work together, but Raju leaves after 2 days and Vicky leaves 3 days before the work is completed. In how many days is the work completed?
43/4 days?
R+V+T 1 day work = (6+5+4) / 60 = 1/4
T 1 day work = 1/15
R+V+T 2 days work = 1/2
T 3 days work = 1/5
Remaining work = 1 - (1/2 + 1/5) = 3/10
V+T 1 day work = (12+15) / (12*15) = 3/20
V+T 2 days work = 3/10
V+T can do 3/10 work in 2 days.
R+V+T can do 1/2 work in 2days.
T can do 1/5 work in 3 days.
*So the work will complete in* 2+2+3 = *7 days.*
total work 2+2+1.8=5.8days
7 days
4 day
owsome😊😊
Thanks Rohit
1/x + 1/y = 1/9
1/y + 1/z = 1/18
1/z + 1/x = 1/12
1/x + 1/y + 1/z = 1/8
They can finish the job in 8 days, working together.
