In the following question below are given three statements followed by three conclusions. Taking the given statements to be true even if they seem to be at variance from commonly known facts, read all the conclusions and then decide which of the given conclusion logically follows the given statements. Statements: Some cycles are bikes. No bikes are cars. Some cars are buses. Conclusions: I. Some Buses are cycles. II. No buses are cycles. III. Some bikes are cycles.?

Option 2 : either I or II and conclusion III follow.

The least possible Venn diagram is given below:

Conclusions:

I. Some Buses are cycles → False (the possibilities are true but not defined). 

II. No buses are cycles → False (the possibilities are true but not defined).

III. Some bikes are cycles → True (It is defined).

In conclusion, I and II are complementary pairs so either or case is followed.

Hence, the correct answer either I or II and conclusion III follow.
