**(i).** A, B, C, D, E and F are six students in a class.**(ii).** B and C are shorter than F but heavier than A.**(iii).** D is heavier than B and taller than C.**(iv).** E is shorter than D but taller than F.**(v). **F is heavier than D.**(vi).** A is shorter than E but taller than F.

**Which of the following groups of friends is shorter than A ?**

** Option:**

**A.**B, C only

**B.**D, B, C only

**C.**E, B, C only

**D.**F, B, C only

**E.**None of these

**Answer: D . F, B, C only**

** Justification:**

In terms of height, we have :

B < F, C < F, C < D, E < D, F < E, A < E, F < A.

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

Thus, the sequence becomes :

B < C < F < A < E < D or C < B < F < A < E < D.

In terms of weight, we have :

A < B, A < C, B < D, D < F.

So, A < B < D < F, A < C.

Thus, the sequence becomes :

A < C < B < D < F or A < B < C < D < F or A < B < D < C < F.

Clearly,

**F, B and C are shorter than A.**
