Sir I have a doubt in last line where u write 25/8+9+8/12 where from this last 8 come ist 8 from the multiple of cross 2×4 than 9 from3×3 but 4×4 becomes 16 than where from this 8 come I think it should be 16 can u explain me sir plz
A can do 1/3 of a work in 5 days and B can do 2/5 of the work in 10 days. In how many days both A and B together can do the work. Please discuss these type questions with trick. 👍
Total work= efficiency X time For A: 1/3= eff. X 5days Eff of A= 1/15 For B: 2/5= eff. X 10days Eff. Of B= 1/25 A and B together= 1/15+1/25= 8/75 Time is inversely proportional to efficiency so , they take 75/8 days to complete the work together.
Sir how is it possible If we reduce the no. of labourer in 2nd case then it will take more days to done the work..means it will take more than 25 days to do the same...
Sir i can't solve this question using the same method that you've used,please help... 1) If 1 man or 2 women or 3 boys can complete a piece ofworkin 88 days, then 1 man, 1 women and 1 boy together will complete it in how many days.???
X, Y, Z can finish a piece of work in 20 ,30, and 40 days respectively. If X left the work after working for 5 days, in how many days can Y and Z together complete the remaining work ?
Take lcm of 20 30 and 40 =120 which gives total number of works. So x can complete 6 units work in 1 day ,y can complete 4 units work in 1 day and z can do 3 units a day. Together they can do 13 units work a day.after working 5 days together they complete 65 units work .when x left work after 5 days, Remaining work is 120-65=55units and y and z can do 7 units per day together so they can complete remaining work in55 /7 days.
Sanjeev can build a wall in 20 days and Parveen can demolish the same wall in 30 days. If they work on alternate days with Sanjeev starting the job on the 1st day, then in how many days will the wall be built for the first time
Productivity = Work / Time S = W/20 P = - W/30 let's say sanjeev worked for 'x' days, Parveen worked for 'y' days S * x + P * y = W we need to find x+y W/20 * x - W/30 * y = W x/2 - y/3 = 10 3x - 2y = 60 since we need to find two variables, but we have only one equation : we should go for trial and error. let's say they worked for equal number of days ( x==y) 3x - 2x = 60 … so 'x' & 'y' are close to 60 ok. let's try x=60, y=60 and check whether LHS = RHS LHS = 3x - 2y = 3*60 - 2 *60 = 60 = RHS so, x=60, y=60 are correct answer is x+y = 120 days. for more explanation, checkout the playlist ua-cam.com/video/k7I_KvoM0gE/v-deo.html
From your first example if I twist the question to "If 20 men or 24 women or 40 boys can do a job in 12 days , how many men working with 6 women and 2 boys can complete the work in 32 days? What is the trick or solution?
You have to apply the same trick for this question also. Just put x where you need number of man and put this equation = 32 , and solve it. Your answer will be 1.5 man.
sir ji i m sorry but agar 58 and 1/3% agar A n B banda work finish kare in 7 days jabki B is 40% more efficient than A then iss type ka faster tricks specially for qty 1 and qty 2 comparison tricks ho to pllz bataiye sir.
What is the largest six digits number which when divided by 3,8,10 &15 leaves the remainder 1,6,8&13 respectively. Please sir , explain as soon as possible with trick its urgen.
Sir. The question is 2 men 3 boys can do a piece of work in 10days while 3 men 2 boys can do same work in 8 days. In how many days can 2 men and 1 boy do work?
acc to the ques, 3M = 4W = 6B (as all can do the work in 25 days) 2M + 3W + 4B =? let's convert this whole equation into women then 3M = 4W Multiplying by 2 and dividing by 3 on both the sides 2M = 8/3 W now let's take out the value of 4B 6B = 4W multiplying by 2 and dividing by 3 4B = 8/3 W putting the values in the equation 2M + 3W+ 4B 8/3W + 3W + 8/3 W 25/3W now. 4W X 25days = 25/3 W X ?days = 12days
Q)8men or 10women or 10children were earn Rs1024. In how many days 6men or 5women and 4children will earn Rs768?🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼Sir Plzz answer this question.❤️❤️its my kind request.I have asked many but none can answer. ANSWER: 2
A and B undertake to do a piece of work for Rs.600. A alone can do it-in 6 days while B alone can do it in 8 days. With the help of C, they finish it in 3 days. Find the share of each.
Eff(A)=8, Eff(B)=6. Total work=48 Let Eff(C)=x work done by (A+B+C) in 3 days=Total work => (8+6+x)3=48 42+3x=48 3x=6 x=2 Eff(C)=2 Share will be Distributed acc to Eff. Share of C=(600/8+6+2)2=Rs 75
It takes Ali 30 minutes to mark a paper. Aslam only needs 25 minutes to mark a paper. If they both start marking papers at 10:00 AM, at what time they will finish marking at the same time?
A and B working separately can do a piece of work in 9 and 12 days respectively, If they work for a day alternately, A beginning, in how many days, the work will be completed?
I noticed one thing in this type of question. LCM of 'or' variables will be the ans of the Question

Bilkul sahi kaha aapne bhai sahab
A can do 1/3 of a work in 5 days and B can do 2/5 of the work in 10 days. In how many days both A and B together can do the work. Please discuss these type questions with trick. 👍
bro do you have PGCET tommorow or what .????
A in 15day
B in 25day LCM 75 efficiencies are 5 and 3
75÷8 days
Total work= efficiency X time
For A: 1/3= eff. X 5days
Eff of A= 1/15
For B: 2/5= eff. X 10days
Eff. Of B= 1/25
A and B together= 1/15+1/25= 8/75
Time is inversely proportional to efficiency so , they take 75/8 days to complete the work together.

X, Y, Z can finish a piece of work in 20 ,30, and 40 days respectively. If X left the work after working for 5 days, in how many days can Y and Z together complete the remaining work ?
Roshan Sah ans is 47 1/4 or 47.5 days
Correct ans is 55/7 days
Rupesh Raj how???🤔
Take lcm of 20 30 and 40 =120 which gives total number of works. So x can complete 6 units work in 1 day ,y can complete 4 units work in 1 day and z can do 3 units a day. Together they can do 13 units work a day.after working 5 days together they complete 65 units work .when x left work after 5 days,
Remaining work is 120-65=55units and y and z can do 7 units per day together so they can complete remaining work in55 /7 days.
55/7 is ans
Yo sir you are the best 💯💪💪💪 thanks for this formulae
Very Good Trick... 👍👍👍
It's is the most concept.thank u so much sir
Finally the lcm of men or women or boys is the ans. Of question do you notice this
Not in every case

Sanjeev can build a wall in 20 days and
Parveen can demolish the same wall in 30 days. If they work
on alternate days with Sanjeev starting the job on the 1st day,
then in how many days will the wall be built for the first time
S +20 +3
60
P -30 -2
--------
1
In 2 days 1 unit is done
In 120 days 60 units will be done
Is this the correct answer?
Productivity = Work / Time
S = W/20
P = - W/30
let's say sanjeev worked for 'x' days, Parveen worked for 'y' days
S * x + P * y = W
we need to find x+y
W/20 * x - W/30 * y = W
x/2 - y/3 = 10
3x - 2y = 60
since we need to find two variables, but we have only one equation : we should go for trial and error.
let's say they worked for equal number of days ( x==y)
3x - 2x = 60 … so 'x' & 'y' are close to 60
ok. let's try x=60, y=60 and check whether LHS = RHS
LHS = 3x - 2y
= 3*60 - 2 *60
= 60
= RHS
so, x=60, y=60 are correct
answer is x+y = 120 days.

hi sir how it will take 8+9+8
Thank you so much sir.........
Nice sir!!!!!
3*4 how it can be 8 bro can u plz explain,,,in 3 table how many times 12 goes = 4 like diz 4+3+2=9
Same dout
Same bro how?
Sir how you calculated 8+9+8.
Please tell me
Me too I didn't get it
Where from 898 Cam??
Take LCM
Check the table of biggest number to take Lcm i.e 6
12 comes in table of 3,4,6 so lcm 12
2*4=8
3*3=9
4*2=8
By multiplying numerators
Thank you sooooo much
Wow , amazing, sir,nice, explanation.sir
acc to the ques,
3M = 4W = 6B (as all can do the work in 25 days)
2M + 3W + 4B =?
let's convert this whole equation into women
then
3M = 4W
Multiplying by 2 and dividing by 3 on both the sides
2M = 8/3 W
now let's take out the value of 4B
6B = 4W
multiplying by 2 and dividing by 3
4B = 8/3 W
putting the values in the equation
2M + 3W+ 4B
8/3W + 3W + 8/3 W
25/3W
now.
4W X 25days = 25/3 W X ?days
= 12days
Thank you so much. I was looking for the logic and got this! thank youuuu

Thank you sir,thank you so much
A and B undertake to do a piece of work for Rs.600. A alone can do it-in 6 days while B alone can do it in 8 days. With the help of C, they finish it in 3 days. Find the share of each.
Eff(A)=8, Eff(B)=6. Total work=48
Let Eff(C)=x
work done by (A+B+C) in 3 days=Total work
=> (8+6+x)3=48
42+3x=48
3x=6
x=2
Eff(C)=2
Share will be Distributed acc to Eff.
Share of C=(600/8+6+2)2=Rs 75
Excellent 👍👍👍👍👍👍
