Among 6 persons A, B, C, D, E and F, it is known that; A is taller than at-least 3 persons. C is taller than B, who is taller than exactly 1 person. D is not shorter than C. E is taller than A and D is shorter than A. Who is 4th shortest person among all?

D

6 persons A. B, C, D, E and F

1) A is taller than at-least 3 persons.

So, A _> _> _ (Atleast)

2) C is taller than B, who is taller than exactly 1 person.

So, _> _> _> C> B> _

3) D is not shorter than C.

So, D> C

4) E is taller than A and D is shorter than A.

So, E> A> D

5) Combining all the statements together, we get:

So, E > A> D> C> B> _

6) Only F is left, so it will take the vacant position.

So, the final arrangement is:

So, E > A> D> C> B> F

Therefore, D is the 4th shortest person among all
