What is the area of a circle with radius 7 cm using π = 22/7?

  • A154 cm²
  • B144 cm²
  • C164 cm²
  • D174 cm²
Permalink
Correct Answer: Option A — 154 cm²
Explanation: Area = π × r² = (22/7) × 7 × 7 = 22 × 7 = 154 cm². Using π = 22/7 is standard in competitive exams for ease of calculation. Circle area formulas are applied in problems involving fields circular tracks rings and cross-sections of cylindrical or spherical objects.

A shopkeeper buys an item for Rs 200 and sells it for Rs 250. What is the profit percentage?

  • A20%
  • B25%
  • C30%
  • D35%
Permalink
Correct Answer: Option B — 25%
Explanation: Profit = 250 - 200 = Rs 50. Profit percentage = (50 ÷ 200) × 100 = 25%. Profit and loss percentage calculations are heavily tested in competitive exams. A key distinction is that profit percentage is always calculated on cost price unless stated otherwise which is a common source of error.

If a train travels 120 km in 2 hours what is its speed?

  • A50 km/h
  • B60 km/h
  • C70 km/h
  • D80 km/h
Permalink
Correct Answer: Option B — 60 km/h
Explanation: Speed equals distance divided by time: 120 ÷ 2 = 60 km/h. The speed-distance-time relationship is one of the most tested topics in competitive exams. Problems often require finding any one variable when the other two are given including problems involving relative speed average speed and time calculations.

What is the perimeter of a rectangle with length 8 cm and width 5 cm?

  • A26 cm
  • B28 cm
  • C30 cm
  • D32 cm
Permalink
Correct Answer: Option A — 26 cm
Explanation: Perimeter of rectangle = 2×(length + width) = 2×(8+5) = 2×13 = 26 cm. Perimeter measures total boundary length. Rectangle perimeter formulas are used in fencing construction and measurement problems and appear regularly in entry-level competitive exam geometry sections alongside area and diagonal calculations.

Which of the following is a prime number?

  • A1
  • B9
  • C15
  • D17
Permalink
Correct Answer: Option D — 17
Explanation: 17 is a prime number having exactly two factors: 1 and itself. The number 1 is neither prime nor composite. 9 equals 3×3 and 15 equals 3×5 so both are composite. Prime numbers are fundamental in number theory cryptography and competitive exam questions on divisibility HCF LCM and factorization.

The sum of angles in a triangle is?

  • A90 degrees
  • B180 degrees
  • C270 degrees
  • D360 degrees
Permalink
Correct Answer: Option B — 180 degrees
Explanation: The interior angles of any triangle always sum to exactly 180 degrees. This fundamental theorem of Euclidean geometry applies to all triangles whether equilateral isosceles scalene right-angled or obtuse. It is frequently used to find unknown angles in triangles and polygons and is foundational for all geometry questions.

What is the LCM of 4 and 6?

  • A12
  • B18
  • C24
  • D36
Permalink
Correct Answer: Option A — 12
Explanation: The Least Common Multiple of 4 and 6 is 12. For 4 (2²) and 6 (2×3) LCM = 2²×3 = 12. LCM is the smallest positive integer divisible by both numbers. It is used in adding fractions finding common denominators and solving problems involving cycles or periodic events in competitive exam arithmetic.

If x + 5 = 12 what is the value of x?

  • A5
  • B6
  • C7
  • D8
Permalink
Correct Answer: Option C — 7
Explanation: Solving x + 5 = 12: subtract 5 from both sides giving x = 7. This is a basic linear equation in one variable. Linear equations form the foundation of algebra and appear in virtually every competitive exam. Mastering quick solutions to such equations is essential for tackling more complex word problems accurately.
