Question 32

Who owns the Nokia handset?

Solution

Let's tabulate the conditions one by one.

Since we have ten handsets, we have two cases
1: T owns 2 handsets
2: T owns 1 handset
Case 1 :
If T owns 2 handsets, then S owns 4 handsets
But Q owns handsets of three different brands.
So we are left with only 1 handset to be given between P and R.
This case will not serve the purpose
Case 2: T owns 1 handset.
If T owns 1 handset, then S owns 2 handsets
Since the person who owns Nokia does not own any other handsets
It cannot be T as T and R have at least one handset brand in common
It cannot be Q as it owns three different brands.
It cannot be S as it has 2 handsets and the person who owns Nokia doesn't own any other handsets.
So it has to be P : P owns a Nokia handset.
