If 15 men, working 9 hours a day, can reap a field in 16 days, in how many
days will 18 men reap the field, working 8 hours a day?

• Since the number of days is to be found out , we compare each item with the number of days.
  More men , less days (Indirect)
  Less working hours More days (Indirect)
  Men 18 : 15} ..
  Working Hours 8 : 9 } .. 16 : x
  18 x 8 x X = 15 x 9 x 16 or x=15
  Required Number of days = 15

• m1*d1*h1=m2*d2*h2
  substitute u wl get d2=15
• 11 years agoHelpfull: Yes(11) No(0)
• 15*9*16=x*18*8
  solving,
  x=15.

• 15 days are inverse propotional to hrs and mens so 18*8*x=15*9*16=15 so ans is 15

• 15 days..........
  at first 15 men will complete in 16dys if they work for 9 hours in a day
  total work hours = 15*9*16=2160
  if 18 men works for 8 hrs in a day
  total work hours in a day= 18*8=144
  total works 2160
  total days= 2160/144= 15days

• 15*9*16=18*x*8
  simple formula:
  M1*T1=M2*T2

• 15*9*16=18*8*x
  x=15ans.

• very easy way of solving this question.
  18 x 8 x X = 15 x 9 x 16
  Required Number of days = 15

• men hr days work
  15 9 16 1
  18 8 x 1
  so
  (15*9*16)/1=(18*8*x)/1
  therefore
  X=15

• 15 days answer. one formula is there that is m1*h1*d1=m2*h2*d2 so 15*9*16 = 18*8*d2 solve it u can get the answer
