Answer 2

Given

• U = {1,2,3,.........,50}
• A = {x : x is divisible by 2 and 3)
• B = {x : x = n², ne N)
• C = {x: x is a factor of 42)

Solution

(i) Write the sets A, B, C in roster form

A = {6,12,18,24,30,36,42,48}

B = {1,4,9,16,25,36,49}

C = {1,2,3,6,7,14,21,42}

(ii)State whether A is equal to C

• Elements of set A = 6,12,18,24,30,36,42,48
• Elements of set C = 1,2,3,6,7,14,21,42
• Each element of A is not as same as the element in C
• Since all elements of set A&C are not same
• A is not equal to C. ie. A ≠ C
