Chapter 2: Fractions and Decimals

Ques. What is the sum of 3/4 and 2/5?

A) 1/2

B) 11/20

C) 7/10

D) 1 1/20

Ans. B) 11/20

Explanation: To find the sum of fractions, we need a common denominator. Here, the common denominator is 20. So, 3/4 + 2/5 = 15/20 + 8/20 = 23/20 = 1 3/20 = 1.15

Ques. Which of the following is a terminating decimal?

A) 1/3

B) 2/5

C) 3/8

D) 4/25

Ans. D) 4/25

Explanation: A terminating decimal is a decimal that ends. 4/25 = 0.16, which terminates.

Ques. Simplify: 0.6 ÷ 0.2

A) 3

B) 0.3

C) 30

D) 0.03

Ans. A) 3

Explanation: To divide decimals, move the decimal point in the divisor to make it a whole number. So, 0.6 ÷ 0.2 = 6 ÷ 2 = 3

Chapter 5: Quadratic Equations

Ques. What is the solution to the quadratic equation x^2 – 5x + 6 = 0?

A) x = 2, x = 3

B) x = 3, x = 2

C) x = 1, x = 6

D) x = 6, x = 1

Ans. A) x = 2, x = 3

Explanation: Factor the quadratic equation x^2 – 5x + 6 = 0 to (x – 2)(x – 3) = 0. So, x = 2 or x = 3.

Ques. Which of the following is a factor of x^2 – 9?

A) (x + 3)

B) (x – 3)

C) (x + 2)

D) (x – 2)

Ans. B) (x – 3)

Explanation: x^2 – 9 factors to (x + 3)(x – 3).

Ques. Solve for x: 2x^2 – 5x – 3 = 0

A) x = -1, x = 3/2

B) x = 3, x = -1/2

C) x = 1, x = -3/2

D) x = -3, x = 1/2

Ans. A) x = -1, x = 3/2

Explanation: Solve 2x^2 – 5x – 3 = 0 using the quadratic formula to get x = -1 or x = 3/2.

Chapter 8: Mensuration

Ques. Find the perimeter of a rectangle with length 8 cm and width 5 cm.

A) 26 cm

B) 18 cm

C) 16 cm

D) 30 cm

Ans. A) 26 cm

Explanation: Perimeter of a rectangle = 2(length + width) = 2(8 + 5) = 2(13) = 26 cm

Ques. Calculate the area of a circle with radius 4 cm.

A) 16π cm²

B) 8π cm²

C) 32π cm²

D) 4π cm²

Ans. A) 16π cm²

Explanation: Area of a circle = πr^2 = π(4)^2 = 16π cm²

Ques. What is the volume of a cube with side length 3 cm?

A) 9 cm³

B) 27 cm³

C) 18 cm³

D) 36 cm³

Ans. B) 27 cm³

Explanation: Volume of a cube = side^3 = 3^3 = 27 cm³

Chapter 11: Probability

Ques. If a fair six-sided die is rolled, what is the probability of rolling a prime number?

A) 1/2

B) 1/3

C) 2/3

D) 1/6

Ans. B) 1/3

Explanation: Prime numbers on a die are 2, 3, and 5. So, probability = 3/6 = 1/2

Ques. A bag contains 4 red, 3 blue, and 2 green marbles. What is the probability of drawing a blue marble?

A) 1/3

B) 3/9

C) 1/4

D) 3/8

Ans. B) 3/9

Explanation: Probability of drawing a blue marble = Number of blue marbles / Total number of marbles = 3/9 = 1/3

Ques. If the probability of an event A is 0.4, what is the probability of the complement of A?

A) 0.6

B) 0.4

C) 0.2

D) 0.8

Ans. A) 0.6

Explanation: Probability of the complement of A = 1 – Probability of A = 1 – 0.4 = 0.6
