Detailed explanation-1: -The universal set U consists of all natural numbers, such that, U = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ….. Therefore, as we know, all the even and odd numbers are a part of natural numbers. Therefore, Set U has all the elements of Set A and Set B.
Detailed explanation-2: -We can observe here that the puzzle is on the logic of number written in words. So, the number 6 will be equal to three as it has three letters in its word. Hence, The required answer is 3.
Detailed explanation-3: -The primes up to 50 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47. The sequence of gaps-the differences between each prime and the next-is 1, 2, 2, 4, 2, 4, 2, 4, 6, 2, 6, 4, 2 and 4.
Detailed explanation-4: -Hence, the number of elements of the power set of A is 8.
