If a person has two rectangular fields. The larger field has thrice the length and 4 times the width of the smaller field. If the smaller field has a length 50% more than the width.If a person takes 20 minutes to complete one round of a smaller field then what is the time required to complete one round of a larger field ?  Choose the correct choice
A) 69 minutes
B) 68 minutes
C) 58 minutes
D) 48 minutes
E) 67 minutes
Let the width of the smaller rectangle is 4 units   then, the length of the smaller rectangle is 6 units(that is 50% more than the width)   Now the perimeter of the rectangle is 2(6+4)=20units   So, 20 units is covered in 20 units, implies covers one unit in one minute   So Now coming to the larger rectangle   The Width =16Units, Length =18units, perimeter=2(16+18)68 units   Thus, to cover the larger field, 68 minutes required to cover the rectangle.   ANSWER:68 minutes
