4 men and 10 women complete a task in same time as 6 men and 6 women do. How much fraction of work will be finished in same time if 5 men and 5 women will do that task.
A)5/6 B)6/13 C)7/9 D)11/12 E)None

• 4M+10W=6M+6W
  4W=2M
  1M=2W
  So,
  4M+10W=4*2+10
  4M+10W=18=6M+6W
  5M+5W=5*2+5=10+5=15
  The fraction of work finished is
  15/18=5/6

• let
  4m + 10w = x..........(i)
  6m + 6w = x............(ii)
  &
  5m + 5w = y .............(iii)
  equating (ii) & (iii)
  => y = 5x/6........ans
