How much time will Ravindra take to complete one round, cycling around the boundary of a circular ground ?
I. Speed of cycling is 12 kmph
II. Diameter of the ground is 700 metres

if the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question

if the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question

if the data either in statement I alone or in statement II alone is sufficient to answer the question.

if the data in both the statements I and II together are not sufficient to answer the question.

if the data in both the statements I and II together are necessary to answer the question.

Answer : Option E

Explanation :

From statement I,

Speed = 12 kmph

= $12 imes frac{5}{{18}} = frac{{10}}{3}$ m/sec.

From statement II,

Circumference of ground

$= frac{{22}}{7} imes 700$ = 2200 metres

When both statements are combined, the required time can be determined, that is,

Time = $frac{{{ m{Distance}}}}{{{ m{Speed}}}}$

$= frac{{2200 imes 3}}{{10}}$ = 660 seconds
