 Hi and welcome to the session. I'm Priyanka and let us discuss the following question. It says, let A and B be two sets such that number of elements in set A are three and number of elements in set B are two. If x, 1, y, 2 and z, 1 are in A cross B, find A and B where x, y, z are distinct elements. Let's just start with our solution. Here we are given that number of elements in set A is equal to 3, number of elements in set B is equal to 2. Also we have number of elements in A cross B is equal to this, 1, y, 2, z, 1. These are the ordered pair which we are given. We know that the first of element of the ordered pair belongs to the first set. So we can have that it is equal to 3 and we can write that it is equal to x, y, z as it is given to us. They are distinct elements whereas number of elements in set B are given to us as 2 and if you carefully analyze we have 1, 2, 1. So we have 1, 2. So this is our required answer that is x, y, z are the elements in set A and the elements in set B are 1, 2. So this is our required answer. I hope you enjoyed the session. Take care.
