Easy methods or syllogism equation tricks leads to wrong answer in this type of questions.



From above diagrams we have seen there are cases of conclusions being both right and both wrong.
Any of the first 4 options is not completly correct.
We have to choose the best suited option in the case.
Only Option (5) follows.

4.  Statements :
Some schemes are offers.
Some offers are discounts.
No discount is a loan.
Conclusions:
I, Those offers which are discounts can never be loans.
II. Some loans are definitely schemes.
(1) Only Conclusion I follows
(2) There is possibility that all schemes are loans
(3) Only Conclusion II follows
(4) Either Conclusion I or Conclusion II follows
(5) Neither Conclusion  I  nor Conclusion II follows

Ans : (1)  Only Conclusion I follows

Solution:














Statement 3 justifies Conclusion I. (No discount is a loan)
But Conclusion II is not always true. So it it not correct as the word " definitely" is used.
From the answer list Option 1 is definitely true. But Option 2 is also a chance.
For selecting the most suited answer, we can neglect the Option 2 as it is only a possibilty which is not mentioned in the Statement.
So only Option (1) correct.

5.  Statements :
No car is hotel.
All lodges are hotels.
No lodge is house.
Conclusions:
I. Some houses are not lodges.
II. No lodge is car.
(1) There is possibility that all houses are cars.
(2) Only Conclusion I follows
(3) Only Conclusion II follows
(4) Neither Conclusion I nor Conclusion II follows
(5) Both Conclusion I and Conclusion II follow

Ans : (5)  Both Conclusion I and Conclusion II follow

Solution:


Conclusion I is justified by Statement 3.
Concluison II is justified by Statements 1 and 2.

Option (1) is confusing. But we can neglect it as not justified by the statement where already justified option exist. It will be as below.
