 Hello and welcome to the session. In this session, we shall solve the following question and the question says, which of the following sets are equivalent sets? First part is, B is equal to the set containing the elements A, E, I, O, U. C is equal to the set containing the elements A, B, C, D, E. Second part is, A is equal to set of letters of the word tutor. D is equal to set of letters of the word paper. Third part is, M is equal to the set containing the word September. W is equal to the set containing the words Saturday, Sunday. And the fourth part is, E is equal to the set containing the elements 2, 4, 6, 8, 10 and F is equal to the set containing the elements 3, 6, 9, 12, 15. Before we start solving the question, let us first review what are equivalent sets? Equivalent sets are two sets that contain same number of elements which may or may not be identical. Also note that equivalent sets are different from equal sets as equal sets are the sets which have same number of elements and the elements are exactly identical. So this is a key idea for this question and using this key idea, we will solve our question. Let's start the solution now. First part is, V is equal to the set containing the elements A, E, I, O, U and C is equal to the set containing the elements A, B, C, D, E. Here we can see that both the sets V and C contain same number of elements that is 5 as the number of elements in both the sets is 5. Therefore, V and C are equivalent sets. Now the second part is, A is equal to set of letters of the word tutor and B is equal to set of letters of the word paper. Let us first list down the elements of the sets A and V. Set A is equal to the set containing the elements T, U, O, R and set B is equal to the set containing the elements P, A, E, R. Both the sets A and B have 4 elements hence A and B are equivalent sets. Now the third part is M is equal to the set containing the word September and W is equal to the set containing the words Saturday, Sunday. We can see that the set M and W do not have same number of elements as M has one element and W has two elements. So M and W are not equivalent sets. The fourth part is E is equal to the set containing the elements 2, 4, 6, 8, 10, F is equal to the set containing the elements 3, 6, 9, 12, 15. We can see that the set E contains first 5 multiples of 2 and set F contains first 5 multiples of 3. So E and F have 5 elements therefore E and F are equivalent sets. With this we end our session. Hope you enjoyed the session.
