Answer 1

Answer:

A = {x : x is a multiple of 2 and is less than 25}

= {2,4,6,8,10,12,14,16,18,20,22,24}

B = {x : x is a square of natural numbers and is less than 25}

= {1,4,9,16}

C = {x : x is a multiple of 3 and is less than 25}

= {3,6,9,12,15,18,21,24}

D = {x : x is a prime number less than 25}

= {2,3,5,7,11,13,17,19,23}
