Question

To answer the question "who is the youngest person in the group", which of the given statements is superfluous ?

• A. Only (i)
• B. Only (ii)
• C. Only (v)
• D. Either (i) or (iv)
• E. None of these

Answer 1

The correct option is A Only (i)

We first find the sequence of height :

By (iii), we have : M < P.

By (v), we have : P < N.

Now, Rupa is tallest and Kamini is is second in height.

So, the sequence of heights is : M < P < N < K < R.

Now, we determine the age sequence :

By (ii), we have : K < R.

By (iii), we have : P < M.

By (iv), we have : R = M.

By (v), we have : R < N.

So, the sequence of ages is : N < R = M < K < P or N < R = M < P < K.

Clearly, only statement (i) is not necessary.

Hence, the answer is (A).
