What is the area of a triangle with base 10 cm and height 6 cm?

  • A25 cm²
  • B30 cm²
  • C35 cm²
  • D40 cm²
Permalink
Correct Answer: Option B — 30 cm²
Explanation: Area of triangle = (1/2) × base × height = (1/2) × 10 × 6 = 30 cm². This formula applies to all triangles when the perpendicular height is known. For triangles where only sides are given Heron's formula is used. Triangle area calculations are fundamental and appear across all competitive exam geometry sections.

What is 0.25 expressed as a fraction in simplest form?

  • A1/2
  • B1/4
  • C1/5
  • D2/5
Permalink
Correct Answer: Option B — 1/4
Explanation: 0.25 = 25/100 = 1/4 after dividing by 25. Converting between decimals fractions and percentages is fundamental: 0.25 = 1/4 = 25% are equivalent forms. Such conversions appear extensively in competitive exam arithmetic ratio and percentage questions and must be performed quickly and accurately.

What is the sum of first 10 natural numbers?

  • A45
  • B50
  • C55
  • D60
Permalink
Correct Answer: Option C — 55
Explanation: Sum of first n natural numbers = n(n+1)/2. For n=10: 10×11/2 = 55. This formula was famously demonstrated by Gauss. The formulas for sum of natural numbers squares and cubes are essential tools frequently tested in competitive exam questions on arithmetic series and progression problems.

The ratio of boys to girls is 3:2. If there are 30 students how many are girls?

  • A10
  • B12
  • C14
  • D16
Permalink
Correct Answer: Option B — 12
Explanation: Total ratio parts = 3+2 = 5. Girls = (2/5)×30 = 12. Ratio and proportion problems are extensively tested. They require dividing quantities according to ratios and appear in problems about mixtures alloys speed partnership and map scales. Always identify the correct ratio part for the quantity being sought.

A number is divisible by 9 if?

  • AThe last digit is 9
  • BThe sum of digits is divisible by 9
  • CIt ends in 0 or 9
  • DIt is divisible by 3 only
Permalink
Correct Answer: Option B — The sum of digits is divisible by 9
Explanation: A number is divisible by 9 when the sum of all its digits is divisible by 9. For example 729: 7+2+9=18 which is divisible by 9. Divisibility rules for 2 3 4 5 6 7 8 9 10 and 11 are important shortcuts saving significant time in competitive exam arithmetic and number theory questions.

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
