A cow is tethered in the middle of a field with a 14 feet long rope. If the cow grazes 100 sq.ft per day, they approximately what time will be taken by the cow to graze the whole field ? Correct Answer 6 days
Area of the field grazed :$$\eqalign{ & = \left( {\frac{{22}}{7} \times 14 \times 14} \right)sq.ft \cr & = 616\,sq.ft \cr} $$
Number of days taken to graze the field :
$$\eqalign{ & = \frac{{616}}{{100}}\text{days} \cr & = 6\,\text{days}(\text{approx}) \cr} $$
