Very simple Just use MDH Formula - (4×8×5)/x= (2×20×A)/2x So, A = 8hrs ✅ here, A is the no. of daily hours X is the number of sheets. Hope that it helped🤘🏼
In first one 5 hrs a day and there is 4 teacher So they all works 20 hrs per day And they done in 8 days so All answer sheet checked in 20×8 = 160 hrs Now Students are doubled then time taking to be checked answer sheet = 320hrs Now there are two teacher , so we divide it in half and half so one teacher done their work in 160 hrs And they work for 20 days so 160hrs/20 day = they works 8hrs/day Hope it is clear ✨👍🏻
Initially Total no. of teachers=4 Total no. Of days=8 No. Of hrs per day they worked=5 Total no. Of hrs spent=4×8×5=160 Now No.of copies are doubled so no. Of hrs will also be doubled No.of hrs required=160×2=320 Total no. Of teachers=2 Total no. Of days=20 No.of working hrs per day per teacher=320/(2×20) =8 hr which should be the right answer Hope you all understand 😊
I am in only 12th class(PCM) and I really solve this before seeing answer ,muje khud ko believe nahi ho raha 😮 and maine bhi same tarike se solve Kiya 😮
You are right but give the ans in detail like this and you have to add more to do this 4 teacher x 8days x 5 hours=160 Therefore, double students then double work=2x160=320 The teacher will half then the work will double therefore, 2x320=640 For per. Teacher 4/640 = 160 20 day for 1 teacher = 160/20=8
First year = 8 × 5 × 4 = 160 Second year = 160 × 2 = 320 per teacher in second year work hour = 320/20= 16/2 = 8 hours So Work done by single teacher = 8 hours ✌✌
Its really simple, As, they asked for how many hrs.... So, according to maths multiplication rule If we multiply all tha given value of both situation then it must be equal.... Solution.... let hrs = (X). So, 4 x 5 x 8 x 4 = 2 x 8 x 5 x (X) 640 = 80(X) (X) = 640/80 (X) = 8 hrs.... (solved 😅)

4*8d*5h=160hours if number of copies doubled then working time will be=160*2=320 hours if number of teachers are two then per teacher working time will be = 320/2=160 hours Number of days is 20 so per day per teacher working time will be= 160/20=8 hours

Number of students has doubled but number of teachers has halved, so load on each teacher has increased by = 2 x2 = 4 But the days given have increased by = 20/8=2.5 times only. We can see that the days have increased less than the load. So, they need to increase the number of hours per day to do it in 20 days. The factor of increase will be = 4/2.5 So if they were working 5 hours a day before, now they will work = 5x (4/2.5) = 8 Hours a day
In first one 5 hrs a day and there is 4 teacher So they all works 20 hrs per day And they done in 8 days so All answer sheet checked in 20×8 = 160 hrs Now Students are doubled then time taking to be checked answer sheet = 320hrs Now there are two teacher , so we divide it in half and half so one teacher done their work in 160 hrs And they work for 20 days so 160hrs/20 day = they works 8hrs/day Hope it is clear

For the first year no. Of days * no. Of hours * no. Of teachers= 5*8*4=160 For sy 160*2=320 No. Of hours= 320/(teachers*no. Of days) =320/(20*2)=8 hours
For 1st year time taken to cover all the paper i.e.=5*4*8=160hrs(total time ) For next year when the no of student twice of 1st year so time taken to cover all the paper i.e.160*2=320 Then we have to find the no of hrs which takes first teacher in a day :- As 1st process we have to do like 2(no of teacher)*20(total days )*x(time takes per day)=320(total hrs) =>x=320/2*20=8hrs.(Ans)
Ans- 8 hours this is how i did it lets take no. of hours as x 1st year no. of students= 4 no. of teachers= 4 each teacher gets 4 / 4 = 1 paper to check every teacher works 5 hrs a day for 8 days to completely finish checking the paper = each teacher works for 8*5 = 40 hrs in total 1 teacher's 1 hour work = 1 / 40 2nd year no. of students= 8 no. of teachers = 2 each teacher gets 8 / 2 = 4 papers to check each teacher work for x no. of hrs a day for 20 days each teacher works for 20x hrs in total 1 teacher's 1 hour work = 4 / 20x = 1 / 5x 1 / 40 = 1 / 5x 5x = 40 x = 40 / 5 x = 8 8 hrs a day
I think 8 hrs..because on multiplying the no of teacher * no of hours *no. Of days =160 hrs so now no. Of students doubles it means sheets double so we need total of 320 hrs but in the question there is condition that there are only two teachers so they need to work for 8 hrs/day to complete their work in just 20 days....Thank you mam

In first one
5 hrs a day and there is 4 teacher
So they all works 20 hrs per day
And they done in 8 days so
All answer sheet checked in 20×8 = 160 hrs
Now Students are doubled then time taking to be checked answer sheet = 320hrs
Now there are two teacher , so we divide it in half and half so one teacher done their work in 160 hrs
And they work for 20 days so
160hrs/20 day = they works 8hrs/day

Mera answer correct tha ma'am, maine to aapki Puri bat sune Bina hi video pause kr ke answer nikal liya vo bhi without writing!!
First year = 8 × 5 × 4 = 160
Second year = 160 × 2 = 320
per teacher in second year work hour = 320/20= 16/2 = 8 hours
So Work done by single teacher = 8 hours
✌✌
Its really simple,
As, they asked for how many hrs....
So, according to maths multiplication rule
If we multiply all tha given value of both situation then it must be equal....
Solution.... let hrs = (X).
So,
4 x 5 x 8 x 4 = 2 x 8 x 5 x (X)
640 = 80(X)
(X) = 640/80
(X) = 8 hrs.... (solved 😅)

But I think it would be quite difficult to solve in a pressurized situation
Approximately each teacher needs 8 hours per day❤
Time & work concept
Ans: 8 hrs😄It was kinda easy!!!
Number of students has doubled but number of teachers has halved, so load on each teacher has increased by = 2 x2 = 4
But the days given have increased by = 20/8=2.5 times only.
We can see that the days have increased less than the load. So, they need to increase the number of hours per day to do it in 20 days.
The factor of increase will be = 4/2.5
So if they were working 5 hours a day before, now they will work = 5x (4/2.5) = 8 Hours a day

So they all works 20 hrs per day
And they done in 8 days so
All answer sheet checked in 20×8 = 160 hrs
Now Students are doubled then time taking to be checked answer sheet = 320hrs
Now there are two teacher , so we divide it in half and half so one teacher done their work in 160 hrs
And they work for 20 days so
160hrs/20 day = they works 8hrs/day

It is done by MDH formula....
4×8×5=160
So the work is double now....160×2=320
Now by MDH formula
320/2×20=8
For the first year
no. Of days * no. Of hours * no. Of teachers= 5*8*4=160
For sy 160*2=320
No. Of hours= 320/(teachers*no. Of days)
=320/(20*2)=8 hours
Ssc aspirants ne to shorts khtm hone se phle hi mnn me solve kr liye honge😂😂
For 1st year time taken to cover all the paper i.e.=5*4*8=160hrs(total time )
For next year when the no of student twice of 1st year so time taken to cover all the paper i.e.160*2=320
Then we have to find the no of hrs which takes first teacher in a day :-
As 1st process we have to do like
2(no of teacher)*20(total days )*x(time takes per day)=320(total hrs)
=>x=320/2*20=8hrs.(Ans)
8 hours for both teachers and 4 hours for single teacher per day
Nope 8hr for both teachers
Ans- 8 hours
this is how i did it
lets take no. of hours as x
1st year
no. of students= 4
no. of teachers= 4
each teacher gets 4 / 4 = 1 paper to check
every teacher works 5 hrs a day for 8 days to completely finish checking the paper
= each teacher works for 8*5 = 40 hrs in total
1 teacher's 1 hour work = 1 / 40
2nd year
no. of students= 8
no. of teachers = 2
each teacher gets 8 / 2 = 4 papers to check
each teacher work for x no. of hrs a day for 20 days
each teacher works for 20x hrs in total
1 teacher's 1 hour work = 4 / 20x = 1 / 5x
1 / 40 = 1 / 5x
5x = 40
x = 40 / 5
x = 8
8 hrs a day
Easy for SSC aspirants

Total hours 4*5*8 =160
Students double 2*160=320
Two teachers worked 320/2=160
Per day work 160/20 = 8
Can you actually solve this riddle before preparing it ?
I think 8 hrs..because on multiplying the no of teacher * no of hours *no. Of days =160 hrs so now no. Of students doubles it means sheets double so we need total of 320 hrs but in the question there is condition that there are only two teachers so they need to work for 8 hrs/day to complete their work in just 20 days....Thank you mam
