The product of two numbers is 48 and their HCF is 4. What is their LCM?

  • A 12
  • B 16
  • C 24
  • D 48
Permalink
Correct Answer: Option A — 12
Explanation: LCM × HCF = Product of the two numbers. LCM = 48 ÷ 4 = 12. This important formula is frequently tested in competitive exams. It allows rapid calculation of LCM or HCF when the product and one factor are known making it a key shortcut for number theory problems in timed exam conditions.

If 5 workers finish a job in 8 days how many days will 10 workers take?

  • A 2 days
  • B 4 days
  • C 6 days
  • D 8 days
Permalink
Correct Answer: Option B — 4 days
Explanation: Total work = 5×8 = 40 worker-days. With 10 workers: days = 40÷10 = 4 days. Work and time problems rely on the inverse relationship between number of workers and time. They are among the most common question types in competitive exams requiring understanding of work rate as a fundamental concept.

A man walks 4 km North then 3 km East. How far is he from the start?

  • A 5 km
  • B 6 km
  • C 7 km
  • D 8 km
Permalink
Correct Answer: Option A — 5 km
Explanation: This forms a right triangle with legs 4 and 3. Distance = √(4²+3²) = √(16+9) = √25 = 5 km. The 3-4-5 Pythagorean triple is the most commonly used in competitive exams. The Pythagorean theorem a²+b²=c² is applied in distance navigation construction and coordinate geometry problems.

In a right triangle if one angle is 30° what is the other acute angle?

  • A 45°
  • B 50°
  • C 60°
  • D 70°
Permalink
Correct Answer: Option C — 60°
Explanation: Sum of angles = 180°. With 90° and 30° the third angle = 180°-90°-30° = 60°. The 30-60-90 triangle has side ratios 1:√3:2 and is one of the most important special triangles in mathematics. It appears extensively in trigonometry geometry and physics problems in all levels of competitive examinations.

What is the value of log base 10 of 1000?

  • A 2
  • B 3
  • C 4
  • D 5
Permalink
Correct Answer: Option B — 3
Explanation: 3! = 3 × 2 × 1 = 6. Factorial of n is the product of all positive integers from 1 to n. Factorials are fundamental in permutations combinations probability calculations and the binomial theorem. Key values to memorize include 0!=1 1!=1 2!=2 3!=6 4!=24 5!=120 and 6!=720 for fast competitive exam solutions.

If 3x - 7 = 2x + 5 what is x?

  • A 10
  • B 12
  • C 14
  • D 16
Permalink
Correct Answer: Option B — 12
Explanation: Subtract 2x: x - 7 = 5. Add 7: x = 12. Solving linear equations with variables on both sides is a core algebraic skill. Such equations frequently appear in word problems about ages work rates and number relationships in competitive exams. The key step is collecting like terms on each side methodically.

What is the compound interest on Rs 1000 for 2 years at 10% per annum?

  • A Rs 200
  • B Rs 210
  • C Rs 220
  • D Rs 100
Permalink
Correct Answer: Option B — Rs 210
Explanation: CI = P(1+r/100)ⁿ - P = 1000(1.1)² - 1000 = 1210 - 1000 = Rs 210. Compound interest exceeds simple interest because interest is earned on previously accumulated interest. CI problems appear in banking and finance sections of competitive exams and require correct application of the compound interest formula.

Two numbers are in ratio 5:3 and their sum is 40. What is the larger number?

  • A 20
  • B 25
  • C 30
  • D 35
Permalink
Correct Answer: Option B — 25
Explanation: Let numbers be 5x and 3x. Sum = 8x = 40 so x = 5. Larger = 5×5 = 25. Ratio problems requiring algebraic substitution are consistent in competitive exams. Using a common multiplier x to represent ratio parts then solving with the given total sum or difference is the most reliable standard method.

If the simple interest on Rs 1000 for 2 years is Rs 100 what is the rate?

  • A 4%
  • B 5%
  • C 6%
  • D 8%
Permalink
Correct Answer: Option B — 5%
Explanation: SI = (P×R×T)/100 → 100 = (1000×R×2)/100 → 100 = 20R → R = 5%. Simple interest problems are standard in competitive exams. The ability to rearrange the SI formula to find principal rate or time is a key skill. Always identify which variable is unknown and rearrange accordingly before substituting values.

Simplify: (a² - b²) divided by (a - b)

  • A a + b
  • B a - b
  • C a² + b²
  • D ab
Permalink
Correct Answer: Option A — a + b
Explanation: a² - b² factors as (a+b)(a-b) using the difference of squares identity. Dividing by (a-b) cancels that factor leaving (a+b). Recognizing algebraic identities including difference of squares perfect square trinomials and sum or difference of cubes is essential for quickly simplifying expressions in competitive exam algebra sections.
