You’re about to see real previous year questions with step-by-step solutions that will help you understand not just the “what” but the “how” and “why” behind each answer. Ready to build your math confidence and tackle those tricky calculations? Let’s dive in together!

Why Does This Topic Appear in Kerala PSC Exams?

Mathematics questions appear in almost every Kerala PSC exam — from LDC and LGS to Degree-level positions. These foundational topics have been tested consistently for years because they measure your logical thinking and problem-solving speed, both absolutely crucial for administrative roles.

If you’re preparing for any Kerala PSC exam, strengthening your math fundamentals is non-negotiable. Just like the specialized topics covered in Kerala PSC Civil Excise Officer: Special Topics – Previous Questions & Answers Part 8, mastering basic math directly boosts your overall score and confidence on exam day.

Key Concepts You Must Understand

Start with the basics — fractions, percentages, and ratio-proportion are your building blocks. These aren’t just standalone topics; they form the foundation for almost every other math question you’ll encounter. Once you’re solid on these fundamentals, everything else becomes easier to understand and remember.

Time-distance-speed problems and average calculations are equally important and appear frequently in PSC exams. The key is to learn the formulas, but more importantly, understand when and why to use them. Head over to Kerala PSC Maths Questions and Answers Part 2 to explore more advanced concepts once you’ve nailed these essentials.

Smart Study Tips Before You Begin

Don’t just memorize formulas — write them down, say them out loud, and solve problems using them. This multi-sensory approach helps your brain retain information much better than passive reading. Spend at least 10-15 minutes daily on math, even if it’s just solving 3-4 problems carefully rather than rushing through many.

Here’s a game-changer: after solving each problem, ask yourself “Why did I use this method?” and “Could I solve it differently?” This habit trains your mind to think critically, which is exactly what PSC exams test. You can also explore other subject areas like ഭൂമിശാസ്‌ത്രം: ഋതുഭേദങ്ങളും സമയവും- പി.എസ്.സി. ചോദ്യോത്തരങ്ങൾ Part 8 to balance your prep and keep things fresh.

The questions you’ll see here test your ability to work under pressure and apply formulas correctly — exactly what you’ll need to do on exam day. Master these topics, and you’ll notice your overall score climbing significantly!

Key Concepts You Must Understand

Let’s break down the core ideas: First, you need to be comfortable with fractions and ratios — knowing how to simplify and manipulate them is your foundation. Second, understand the relationship between speed, distance, and time; this isn’t just math, it’s real-world problem solving. Third, learn statistical concepts like median (the middle value when numbers are arranged in order) and how to apply formulas for work and speed problems.

Think of these concepts as building blocks. Once you’re solid on the basics, complex problems become much simpler. The key is recognizing which formula to apply in which situation, and that comes from seeing multiple examples and understanding the logic behind them. When you’re ready to explore more advanced topics, resources like geography and time-based questions can also strengthen your analytical thinking.

Smart Study Tips Before You Begin

Here’s my best advice: Don’t just memorize formulas — write them out and understand what each variable means. For example, in the formula M1 × D1 = M2 × D2 (for work problems), understand that you’re essentially saying “total work effort is constant.” This mindset helps you remember and apply formulas correctly even when the question is worded differently.

Practice converting units (like minutes to hours, kilometers to meters) until it becomes automatic — this is where many aspirants lose marks unnecessarily. Set a timer and solve 5-10 problems daily, focusing on accuracy first, speed second. When you’re reviewing, check out similar patterns in other PSC question sets to see how these concepts repeat across exams.

PSC Previous Questions and Answers

Below are the most important questions from previous Kerala PSC examinations on this topic. Read each one carefully!

1. If 1400 x = 1050, then what is the value of x?

A) 1

B) 4/3

C) 4/7

D) 3/4

Answer: D

x= 1050 / 1400 = 3/4

2. If 15 men can complete a work in 12 days, then how many men are required to complete the work in 60 days?

A) 4

B) 3

C) 6

D) 9

Answer: B

M1 × D1 = M2 × D2

15 × 12 = M2 × 60

i.e., 15× 12 ⁄ 60 = 3

3. A person travels for 15 hours, the first half at 21 Km/ hr and the other half at 24 Km/hr. Find the distance travelled.

A) 336 Km

B) 346 Km

C) 224 Km

D) 285 Km

Answer: A

Average speed= 2XY / X + Y

Avg. Speed = 2 × 21 × 24 / 21 + 24 = 1008/ 45 = 22.4

Time: 15hrs

Distance = Speed × Time= 22.4 × 15 = 336 Km

4. The distance covered by a man walking for 20 minutes at a speed of 6 km/hr is

A) 1.8 km

B) 3 Km

C) 2 Km

D) 1.5 Km

Answer: C

Distance = Speed × Time

Time = 20 minutes i.e. 20/60 hours

Therefore, D= 6 × 20/60 = 2

5. √162 / ? =? / √18

A) 62

B) 32

C) 45

D) 54

Answer: D

?² = √ 81 × 2 × √ 9 × 2

9 × 3 × 2 = 54

6. 28, 36, 22, 16, 48, 18, 23. Find the median of these numbers?

A) 28

B) 22

C) 23

D) 36

Answer: C

Write the given series in ascending order- 16, 18, 22, 23, 28, 36, 48. The middle number is 23.

7. If DELHI is coded as CDKHG, then what is the code of KOCHI?

A) LMDGJ

B) MQEJL

C) JNBGH

D) IMBGH

Answer: C

8. A person crosses 800m long street in 6 minutes. What is the approximate speed in kilometer per hour?

A) 8 Km/ hr

B) 6 Km/ hr

C) 10 Km/ hr

D) 9 Km/ hr

Answer: A

Distance = 800m = 800 /1000

Time = 6 minutes = 6/ 60 hr

Speed = Distance / Time= 800 / 1000 × 6 / 60 = 8 Km / hr
