Answer / niveditha
Area of the field grazed = [22/7*14*14]sq.ft. = 616 sq.ft.
Number of days taken to graze the field = 616/100 days
=> 6 days(approx.)

Answer / phani madhav
We do not know what exactly the total area is so by
assuming as 14 feet the total area as a square then it
comes to 196 sqft and as the grazes 100 sqft per day then
the balance 96 sqft it should graze the next day. Rounding
off to the second day we can treat the answer as 2 days.
