If the data given in statement II alone is sufficient to answer the question whereas the data given in statement I alone are not sufficient to answer the question.3). If the data in either statement I alone or in statement II alone is sufficient to answer the question.4). If the data in both the statements I and II is not sufficient to answer the question.

Answer»

Considering statement I:

This statement is not sufficient to answer as we need the ratio of their SPEEDS and it doesn’t matter WHETHER they are travelling in the same direction or opposite.

Statement I ALONE is not sufficient.

Considering statement II:

We know,

Distance covered by TRUCK = 550 m = $(\frac{{550}}{{1000}}km)$

$(Speed = \frac{{Distance}}{{Time}})$

Speed of the truck$(\; = \frac{{550\;km}}{{1000\;min}})$

Speed of the bus$(\; = \frac{{33\;km}}{{45\;min}})$

Ratio of the speed of truck to bus$(\; = \frac{{550}}{{1000}} \times \frac{{45}}{{33}} = \frac{3}{4})$

Statement II ALONE is sufficient, but statement I alone is not sufficient.
