Directions For Questions

Direction: In the following question assuming the given statements to be true, find which of the conclusion among given conclusions is/are definitely true and then give your answer accordingly.

...view full instructions

Statements:

T ≤ R; Y ≥ Z; T > Z; R ≥ K

Conclusions:

I. Z ≤ R

II. R > Y

III. T ≥ K

IV. Z < K

A
Only IV is True

B
None is true

C
Only I and IV are True

D
Only II and IV are True

E
Only II is True

Solution

Given statements: T ≤ R; Y ≥ Z; T > Z; R ≥ K

On combining: Y ≥ Z < T ≤ R ≥ K

Conclusions:

I. Z ≤ R → False (as Z < T ≤ R → R > Z)

II. R < Y → False (as Y ≥ Z < T ≤ R → thus clear relation between R and Y cannot be determined)

III. T ≥ K → False (as T ≤ R ≥ K → thus clear relation between T and K cannot be determined)

IV. Z < K → False (as Z < T ≤ R ≥ K → thus clear relation between Z and K cannot be determined)

So, none is true.
