if 30 men, working 8 hours a day . can finish a piece of work in 24 days, in how many days will 18 men working 10 hours a day will complete the same work

• Work balancing equation :
  =>30*8*24/W=18*10*d/W
  =>d=32days

• =>N1*D1*R1/W=N2*D2*R2/W
  =>N1=30,R1=8,D1=24,,,,,N2=18,R2=10,D2=?
  =>30*24*8/W=18*10*D2/W
  =>D2=32DAYS

• 32
  
  total no of work=5760
  days required to complete the work =total no of work/(18*10)

• m1*d1/w1=m2*d2/w2
  30*24/8=?*18/10
  ==>50 days

• as we know...
  M1*W1*D1*T1=M2*W2*D2*T2 ;
  work will be same for both case. hence W1=W2 ;
  now,
  30*24*8=18*D2*10 ;
  on solving,
  D2= 32.
  so 18 men will take 32 days to finish the same piece of work if they are working for 10 hours a day.
