There are six friends A, B, C, D, E and F are of different ages. A is older than only one friend. C is older than F and A. E is older than C and A. B is older than C and only younger than E. D is not the youngest one and younger than C. How many friends are younger than B? Correct Answer 4

The correct answer is option 2 i.e. 4

i) Here, A is older than only one friend.

- > - > - > - > A >- 

ii) B is older than C and only younger than E i.e.

E > B > - > - > A >- 

iii) C is older than F and A means C > F/A.

iv) E is older than C and A means E > C/A.

so from iii and iv, the order is E > C > F/A.

D is not the youngest one and younger than C means D can’t be the last one so we can put F as the youngest one.

The final order would be E>B>C>D>A>F.

So, from the given order, 4 persons are younger than B.

Hence, the correct answer is 4.
