Reasoning PYQs

The least possible Venn diagram for the given statements is as follows,

Conclusions:

I. No green is red → True (It is definite because only trees are green)

II. Some red are tree → True (It is true because there is definite relation between tree and red)

Hence, Both conclusion (I) and (II) follows.

The least possible Venn diagram for the given question is as follows,

Conclusions:

I. Some Car is box → False (it is possible but not definite because there is no direct/definite relation between car and box, so all the possibilities are true)

II. All Pen being Car is a possibility → False ( Only few Pen is Car)

Hence, No conclusion follows.

Note: Only few → As in the above question only few Pen is Car that means some part of Pen is Car but there is some part of Pen that is definitely not Car

The least possible Venn diagram for the given statements is as follows:

Conclusions:

I. Some foolish are not frooti. → True (As we can see clearly in the diagram that some part of foolish is in Fan and no part of fan is frooti).

II. Some fanta are not fan. → True (As we can see clearly in the diagram that some fanta are frooti and no frooti are fan).

Hence, Both I and II follows.

Additional Information      

Only A are B means → All B are A (A and B can be any object) but no other element can be B.

Only Fanta is Frooti means all Frooti are Fanta but other elements (like Fan and Foolish) can never be Frooti.

The least possible Venn diagram for the given statements is as follows,

Conclusions:

I. No metal is a key → false (it is possible but not definite because there is no relation between metal and key)

II. No key is steel → false (because Some keys are locks and All locks are steel. So, Some keys are steel.)

Hence, neither conclusion I nor conclusion II follows.

10. V departs 1 hour before W. (V = 5 pm - 1 = 4 pm)

 

Except for T, all others depart in pm.

Hence, the correct answer is T.
