iii)P and R do not like the odd-numbered watches.

Means,Pand Rlike the even-numbered watches.

Three even number watches are there namely W2, W4, and W6.

Here, W4 is already liked by Q andP likes prime numbered watch is given.

Only, W2 is a prime number watch from all the even number watches.

Hence, P likes the W2 watch.

Now, R also like even number watch is given and only W6 is left from all the even number watches.

Hence, R likes the W6 watch.
