Sample Bihar Polytechnic Practice Questions

Try these sample questions to review concepts for the Bihar Polytechnic exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1If the product of two numbers is 1080 and their Highest Common Factor (HCF) is 6, what is their Least Common Multiple (LCM)?
A.180
B.6480
C.1086
D.1074
Explanation: The relationship between two numbers and their HCF and LCM is given by: Product of two numbers = HCF × LCM. Therefore, LCM = Product / HCF = 1080 / 6 = 180.
2Solve the linear equation for x: 3x - 5 = 16.
A.7
B.11/3
C.21
D.3
Explanation: Adding 5 to both sides of the equation gives: 3x = 16 + 5 => 3x = 21. Dividing both sides by 3 yields x = 21 / 3 = 7.
3What are the roots of the quadratic equation x² - 5x + 6 = 0?
A.2 and 3
B.-2 and -3
C.1 and 6
D.-1 and -6
Explanation: By factoring the quadratic equation: x² - 5x + 6 = (x - 2)(x - 3) = 0. Solving for x gives x = 2 or x = 3.
4Evaluate the trigonometric expression: sin(30°) + cos(60°).
A.1
B.1/2
C.√3
D.√3/2
Explanation: Using standard values: sin(30°) = 1/2 and cos(60°) = 1/2. Thus, sin(30°) + cos(60°) = 1/2 + 1/2 = 1.
5What is the sum of the interior angles of a regular pentagon?
A.540°
B.360°
C.720°
D.180°
Explanation: The formula for the sum of interior angles of a polygon with n sides is: (n - 2) × 180°. For a pentagon (n = 5), the sum is (5 - 2) × 180° = 3 × 180° = 540°.
6An article bought for ₹400 is sold for ₹460. What is the profit percentage?
A.15%
B.60%
C.12%
D.20%
Explanation: Profit = Selling Price - Cost Price = 460 - 400 = ₹60. Profit Percentage = (Profit / Cost Price) × 100 = (60 / 400) × 100 = 15%.
7Find the distance of the point (3, 4) from the origin (0, 0).
A.5 units
B.7 units
C.25 units
D.1 unit
Explanation: The distance formula from the origin is d = √(x² + y²). For the point (3, 4), the distance is √(3² + 4²) = √(9 + 16) = √25 = 5 units.
8Determine the 10th term of the Arithmetic Progression (AP): 2, 7, 12, 17, ...
A.47
B.52
C.42
D.50
Explanation: In this AP, the first term (a) is 2 and the common difference (d) is 7 - 2 = 5. The nth term formula is a_n = a + (n - 1)d. For the 10th term, a_10 = 2 + (10 - 1) × 5 = 2 + 9 × 5 = 2 + 45 = 47.
9What is the value of tan(45°)?
A.1
B.0
C.1/√3
D.√3
Explanation: By definition and standard values: sin(45°) = 1/√2 and cos(45°) = 1/√2. Therefore, tan(45°) = sin(45°) / cos(45°) = 1.
10Calculate the area of a circle whose radius is 7 cm. (Take π = 22/7)
A.154 cm²
B.44 cm²
C.308 cm²
D.49 cm²
Explanation: The area of a circle is given by the formula A = πr². Substituting the values: A = (22/7) × 7 × 7 = 22 × 7 = 154 cm².
