Solution

The correct options are
A B={prime numbers which are even}
B B={set of circles}
C B= ${x / x ϵ Z}$
(a) $A = ϕ$ .Since null set is a subset of every set so $A \subset B$
All A ,B,C are correct options..

'A' is the set of natural numbers less than 100. 'B' is the subset of 'A' such that 'B' contains two digit numbers from set 'A' which are divisible by exactly two numbers. 'C' is the subset of 'B' such that 'C' contains numbers whose sum of digits is divisible by 2. 'D' is the subset of 'C' such that 'D' contains numbers whose sum of digits is a perfect square or a perfect cube. Then find the median of the set 'D'?
