Q. 4 male farmers and 6 female farmers can cultivate a field in 8 days, while 3 male farmers and 7 female farmers can cultivate the field in 10 days. In how many days 10 female farmers can cultivate the same field?

• WORK DONE IN 1 DAY
  4M+6F=1/8
  3M+7F=1/10
  SOLVING THIS WE GET F=1/400
  SO IN 10 DAYS,WORK DONE IS 10/400,hence female farmers take 40 days to complete the work.

• 32 man day +48 fem day=30 man day +70 fem day
  => 1 man day= 11 fem day
  Total work= 32 man day +48 fem day=32*11 fem day +48 fem day= 400 fem day
  there 10 fem will do it in =400/10=40 days

  Work for single men= 2/5
  10 female farmer works=10(8/5)=16

• 4x + 6y = 1/8
  3x + 7y = 1/10
  18y - 28y =3/8 - 4/10
  10y =1/40
  so ,10 female completes work in 40days...
