Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements:
I. Some bikes are cars.
II. Some cars are trucks.
Conclusions:
I. Some trucks are bikes.
II. No bike is a truck.

Conclusion: I. Some trucks are bikes.

There is not any direct relationship given between 'trucks' are 'bikes'. So the given conclusion does not follow.

Conclusion: II. No bike is a truck.

There is not any direct relationship given between 'trucks' are 'bikes'. So the given conclusion does not follow.

But these conclusions are making complementary pairs(Either or case) where at a time one conclusion is possible.

Either conclusion I or II follows.
