Solution

Two sets are said to be equivalent if they have same cardinal number, i.e., same number of elements in it.

Cardinal number for set P (number of elements in set) will be nP=4.

Cardinal number for set Q (number of elements in set) will be nQ=4.

Since, nP=nQ.

Hence the sets will be equivalent, PQ.
