Questions below are given three statements followed by three conclusions numbered I, II and III. You have to take the given statements to be true even if they seems to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.
Question - 6.
Statements:
I. Some carrots are brinjals.
II. Some brinjals are apples.
III. All apples are bananas.
Conclusions:
I. Some apples are carrots.
II. Some bananas are brinjals.
III. Some bananas are carrots.
Only conclusion I follows
Only conclusion II follows
Only conclusion III follows
All conclusions are follows
Solution:
Some brinjals are apples + All apples are bananas = I + A = I = Some brinjals are bananas.
Conversion
Some bananas are brinjals (I). Hence II follows. But I + I = No conclusion.
Hence, I does not follow and neither does III.

I. All keys are locks.
II. All locks are bangles.
III. All bangles are cars.
Conclusions:
I. Some cars are locks.
II. Some bangles are keys.
III. Some cars are keys.
Only conclusion I follows
Only conclusion II follows
Only conclusion III follows
All conclusions are follows
Solution:
All locks are bangles + All bangles are cars = A + A = A = All locks are cars conversion Some cars are locks (I). Hence I follows.
All keys are locks + All locks are bangles = A + A = A = All keys are bangles conversion Some bangles are keys (I). Hence II follows.
All keys are bangles + All bangles are cars = A + A = A = All keys are cars conversion Some cars are keys (I). Hence III follows.

III. No tree is house.
Conclusions:
I. Some houses are fruits.
II. Some trees are fruits.
III. No house is a fruit.
Only conclusion I follows
Only conclusion II follows
Only conclusion III follows
Only conclusion either I or III Follows.
Solution:
All fruits are leaves + Some leaves are trees = A + I = No conclusion. Hence II does not follow. Neither do I nor III consequently. However, either I or III follows as they form a complementary (I - E) pair.

All conclusions are follows
Solution:
Some mirrors are chairs + All chairs are glasses = I + A = I = Some mirrors are glasses conversion Some glasses are mirrors (I). Hence I follows.
All tables are mirrors + Some mirrors are chairs = A + I = No conclusion. Hence II does not follow.
III follows by converting the first statement.

All boxes are taps + Some taps are machines = A + I = No conclusion. Hence I does not follow.
All calculators are boxes + All boxes are taps = A + A = A = All calculators are taps conversion Some taps are calculators. Hence II follow.
All calculators are boxes (A) conversion Some boxes are calculators (I). Hence III follow.

II. P < F
III. F > L
I∨. L = K
Conclusions:
I. F = K
II. F > K
Only conclusion I follows
Only conclusion II follows
Either Conclusion I or II follows
Neither Conclusion I nor II follows
Solution:
N = P ≤ F ≥ L = K
Hence, F ≥ K. Which means either I or II follows.

Question - 12.
Statements:
I. Z > T
II. T < M
III. M < J
Conclusions:
I. T < J
II. J < Z
Only conclusion I follows
Only conclusion II follows
Either Conclusion I or II follows
Neither Conclusion I nor II follows
Solution:
Z > T < M < J
Which means T < J. Hence I follows.
But Z and J can't be compared. Hence II does not follow.
