If 3 men or 4 women can reap a field in 43 days,how long will 7 men and 5 women take to reap it?

• 3 men->43 days
  1 men->43*3 days
  1 men's 1 day's work =1/(43*3)
  similarly, 1 women's 1 days work = 1/(43*3)
  then 7 men + 5 women = 7(1/(43*3))+ 5(1/(43*3))
  =1/12
  that is the answer is 12 days

• 3M=4W
  (M/W)=(4/3)
  1M capacity 4 & 1W capacity 3 by equating..
  total capacity is 12 & work cmplited in 43 days:
  7M+5W=7*4+5*3=43 capacity &work compited in wt days...?
  12*43/43=12 days
