Statements:
All chocolates are juices.
All juices are medicines.
No juice is a biscuit.
Conclusions:
(I): No medicine is a biscuit.
(II): No chocolate is a biscuit.

  • A.

    Neither conclusion (I) nor (II) follows.

  • D.

    Only conclusion (II) follows.

    ✓ Correct

Answer & Solution

Correct option is D

Given:
​Statements:
All chocolates are juices.
All juices are medicines.
No juice is a biscuit.
Conclusion ​
(I) No medicine is a biscuit → Does not follow, because only juices are stated to be non-biscuits.
(II) No chocolate is a biscuit → Follows, because all chocolates are juices and no juice is a biscuit.
So, Only conclusion (II) follows.
Final Correct Option: (D)
Q2.

Read the given statements and conclusions carefully. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. You have to decide which conclusion(s) logically follow(s) from the given statements.
Statements: All stamp are logo. All stamp are cheque. All stamp are document.
Conclusions (I): All logo are document.
Conclusions (II): Some document are cheque.

  • A.

    Both conclusions (I) and (II) follow

  • B.

    Neither conclusion (I) nor (II) follows

  • C.

    Only conclusion (I) follows

  • D.

    Only conclusion (II) follows

    ✓ Correct

Answer & Solution

Correct option is D

Given:
​Statements:
All stamp are logo.
All stamp are cheque.
All stamp are document.​
Conclusion (I): All logo are document. 
This does not follow. We only know that all stamps are logos and documents, but nothing is said about the remaining logos. Therefore, we cannot conclude that all logos are documents.
Conclusion (II): Some document are cheque. 
Since all stamps are both documents and cheques, the stamps form a common group. Hence, some documents are cheques.
Final Answer: (D) Only conclusion (II) follows
Q3.
Read the given statements and conclusions carefully. Assuming that the inform a on given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusion(s) logically follow(s) from the statements.

Answer & Solution

Correct option is A

Statements:
1. All hens are juices.
2. Some juices are nests.
3. All pins are nests.
From the given information possible Venn diagram is as follows.
​Conclusions:
I. Some pins are hens. (False, there is no direct connection between pins and hens).
II. Some pins are juices. (False, the overlap between juices and nests does not guarantee a relationship between pins and juices).
Neither conclusion (I) nor (II) follows.
Thus, correct option is (a).
Q4.

Answer & Solution

Correct option is A

Given,
Statements:
All waters are liquids.
All liquids are juices.
All juices are fruits.

Conclusions:
(I) All waters are fruits → Follow (Because, water is a liquid, and all liquids are juices, and all juices are fruits, this means water must also be a fruit).
(II) Some fruits are liquids → Follow (Because, all liquids are juices and all juices are fruits, this means some part of fruits includes liquids).
So, both conclusions (I) and (II) logically follow.
Thus, the correct option is: (a)

Answer & Solution

Correct option is D

Statements:
I. All ovals are bins.
II. No bin is a car.
III. No bin is a plum.
According to the given statements, the possible Venn diagram is as follows:
Let's analyze the conclusions:
Conclusion (I): No oval is a car. (True) - From the Venn diagram, it is evident that all ovals are bins and no bin is a car. o, from this, it can be concluded that no oval is a car. Thus, this conclusion follows.
Conclusion (II): Some plums are cars.  (False) - From the Venn diagram, it is evident that there is no direct relation between plums and cars. So, no definite relation can be drawn. Thus, this conclusion does not follow.
So, only conclusion (I) follows.
Thus, the correct answer is (d).
