total work done=4*8*5=160units
now work=2*160=320units
now,2 men work for 20days,let x be the hours.
therefore, 2*20*x=320
x=8 hours

8*5=40 hrs per men overall 4 men 4*40=160 hrs of work so 40hrs work is 25percentage
for 160hrs of work 2 men will make the work as 80hrs per person for 20 days i.e., 80/20=4hrs per day.

Let a man can do 1 unit of work in 1 hour.
Total units of work = 4 x 8 x 5 = 160 units.
Now work = 2 x 160 = 320 units.
Now 2 men work for 20 days. Let in x hours they have to work per day.
Now total work = 2*x*20 = 40 x
40x = 320 => x = 320/40 = 8 hours.

LET CHECKING EXAM PAPER =W
NOW , MAN ~ W
MAN~ (1/T) , T STANDS FOR TIME
SO, MAN ~(W/T)
SO , (MT/W)= CONSTANT
>(M1T1/W1)=(M2T2/W2)
HERE M1=4, T1= 8*5=40, W1=W, M2=2, T2= 20*X, W2=2W ANS- X=8HOURS PER DAY

Debajyoti Biswas  (7 years ago)

4 men work for 8*5=40 hrs,so total work done=40*4=160
2 men will work for 20 days & check double the papers,so
total work for them will be 2*160=320
2 men work for 20 days & x hrs daily(say)
so,2*20*x=320
or x=8

W=checking the papers
W2=2*W1
w1=M1*D1*H1
w2=M2*D2*H2
the hours required to complete the double no. of papers : H2=(W2*M1*D1*H1)/(W1*M2*D2)
H2=(2W1*4*8*5)/(W1*2*20)
H2=8hours
