Give answer:

a) If only conclusion I follows.

b) If only conclusion II follows.

c) If either conclusion I or II follows.

d) If neither conclusion I nor II follows.

e) If both conclusions I and II follow.

Statements:

K > L ≤ O = P; S ≤ L < Q

Conclusions:

I). S ≤ P

II). Q > K

Detailed Solution: Question 6

I). S ≤ P (S ≤ L ≤ O = P) → True

II). Q > K (Q > L < K) → False

So, only conclusion I follows.

Test: Reasoning Ability - 1 - Question 11

Directions: Study the following information carefully and answer the questions given below.

Arun walks 7m towards east and stops at point Q. From there, he turns 90° in anticlockwise direction and walks for 4m before stopping at S. Then he turns 135° in clockwise direction and walks for ‘x’ m before stopping at R which is exactly east of Q. From R, he walks 5m south and stops at V, from where he turns 90° in clockwise direction and walks 6m before he finally stops at Z, which is exactly south of S.

Q. What is the value of ‘x’?

Detailed Solution: Question 11

Arun’s path creates the following fixed geometric conditions:

  1. R is exactly east of Q → therefore R and Q have the same Y-coordinate.

  2. Z is exactly south of S → therefore Z and S have the same X-coordinate.

Let Q = (0, 0) for convenience.

Since Z lies south of S, their x-coordinates must match:

a − 6 = 0 ⇒ a = 6

Now calculate the distance x=SR:
