Seven friends P, Q, R, S, T, U and V, each has a different age. P is older than only U and R. R is older than U. Q is older than S but younger than T. T is not the oldest among all. The age of how many persons is between the ages of Q and R?
Answer & explanation
Correct answer: option 2
The logic followed here is:
Step 1: P is older than only U and R.
Step 2: R is older than U.
So, P>R>U
Step 3: Q is older than S but younger than T.
So, T> Q>S
Now on combining all the above steps we get:
T> Q> S> P> R> U
Step 4: T is not the oldest among all.
V> T> Q> S> P> R> U
Therefore, The age of two persons is between the ages of Q and R.
