Question
Given:
A = {Natural numbers less than 10}
B = {Letters of the word ‘PUPPET’}
C = {Squares of first four whole numbers}
D = {Odd numbers divisible by 2}.
Find: A ∩ C AND n(A ∩ C)

Solution
Here,
A= {1, 2, 3, 4, 5, 6, 7, 8, 9}
B = {P, U, E, T}
C = {0, 1, 4, 9}
D = { } or Φ
A ∩ C = {1, 4, 9}
n(A ∩ C) = 3
