a) {a, b, c, d, e}

b) {a, b, d, e}

c) {c}

d) {a, b}

{a.b.c.d.e}

6. . If Set A = {a, b, c} and Set B = {b, c, d}, what is A ∩ B?

a) {a}

b) {b, c}

c) {d}

d) {}

what are common -- {b.c}

7. If Set P = {1, 2, 3, 4, 5} and Set Q = {4, 5, 6, 7, 8}, what is P ∩ Q?

a) {1, 2, 3, 4, 5, 6, 7, 8}

b) {4, 5}

c) {1, 2, 3}

d) {6, 7, 8}

common is {4,5}

a) {2, 4}

b) {6, 8}

c) {10, 12}

d) {2, 4, 6, 8, 10, 12} 4

answer b

9. Question 3: If set S = {1, 2, 3, 4, 5} and set T = {4, 5, 6, 7, 8}, what is S ∩ T?

a) {1, 2, 3}

b) {4, 5}

answer B

10. What is the result of the expression 56 - 4 × 2 + (18 ÷ 3) ?

a) 54

b) 55

c) 42

d) 70

Rule of operations need to be followed, it is also called the rule of PEMDAS

( Parentheses, exponents, multiplication and diviison, addition and subtraction)

IN this problem first in brackets ( parentheses) 18/3 = 6

then multiplication  4 x 2 = 8

now the figures are 56-8+6

Now addition and subtraction , the order is the left to right

56-8 = 48

48+6 = 54

11. What is the result of the expression 20 + 5 × 2 - (12 ÷ 4)?

a) 12

b) 47

c) 27

d) 28

Parentheses (P): Evaluate the operation inside the parentheses first.

12÷4=3

The expression becomes:

20+5×2−3

Multiplication (M): Perform the multiplication next.

5×2=10

The expression becomes:

20+10−3

Addition and Subtraction (AS): Perform addition and subtraction from left to right.

20+10=30

The expression becomes:

30−3

30−3=27

The result of the expression 20+5×2−(12÷4) is 27.
