In the following question below are given some statements followed by some 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: No car is scooter All scooters are drums All drums are flute Conclusions: I. Some drums are not car II. All scooters are flutes III. Some flutes are not cars Correct Answer <span style="font-family:mangal,serif">All follow</span>
Given statements are:
No car is scooter
All scooters are drums
All drums are flute
On combining these we get the least possible Venn diagram,

Conclusions:
I. Some drums are not car → True (as given, No car is scooter, So the portion which is a scooter included in Drums can never be car so this is a true statement.)
II. All scooters are flutes → True
III. Some flutes are not cars → True (as given, No car is scooter, So the portion which is a scooter included in flute can never be car so this is a true statement.)
Clearly, all conclusions follow.
