Mastering shortcut tricks ensures a maximum score within a limited time.
List of WB Police SI Arithmetic Expected Questions 2025:
1. Find the mean proportional between 3 and 27?
Answer: 9
Explanation: Mean Proportional = √(3 × 27) = √81 = 9.
2. A shopkeeper marks an article 20% above cost and offers a 10% discount. What is the profit percentage?
Answer: 8%
Explanation: Let CP = 100. MP = 120. SP = 120 – (10% of 120) = 120 – 12 = 108. Profit% = [(108-100)/100] * 100 = 8%.
3. The HCF of 16/81 and 24/108 is what?
Answer: 4/27
Explanation: HCF of fractions = HCF of Numerators / LCM of Denominators. HCF(16, 24) = 8. LCM(81, 108) = 324. So, HCF = 8/324 = 4/27.
4. A man can do a piece of work in 12 days, and B can do it in 15 days. In how many days will they finish it together?
Answer: 20/3 days or 6 ²/³ days.
Explanation: A’s 1 day work = 1/12. B’s 1 day work = 1/15. Together, 1 day work = (1/12 + 1/15) = 9/60 = 3/20. Time taken = 20/3 days.
5. A train 150m long passes a pole in 5 seconds. Find the speed of the train in km/h?
Answer: 108 km/h
Explanation: Speed = Distance/Time = 150/5 = 30 m/s. To convert to km/h, multiply by 18/5. Speed = 30 * (18/5) = 108 km/h.
6. The simple interest on a sum at 10% per annum for 2 years is ₹1200. Find the sum?
Answer: ₹6000
Explanation: SI = (P × R × T)/100 => 1200 = (P × 10 × 2)/100 => 1200 = P/5 => P = ₹6000.
7. Find the area of a triangle with base 12 cm and height 5 cm?
Answer: 30 cm²
Explanation: Area = (1/2) × base × height = (1/2) × 12 × 5 = 30 cm².
8. If the cost price of 12 articles is equal to the selling price of 10 articles, what is the profit percent?
Answer: 20%
Explanation: CP of 12 = SP of 10. Let CP of 1 article = ₹1. CP of 12 = ₹12. SP of 10 = ₹12, so SP of 1 = ₹1.2. Profit% = [(1.2 – 1)/1] * 100 = 20%.
9. A boat goes 12 km downstream in 2 hours when the speed of the stream is 2 km/h. Find the speed of the boat in still water?
Answer: 4 km/h
Explanation: Downstream speed = 12/2 = 6 km/h. Downstream speed = Boat speed + Stream speed. 6 = Boat speed + 2. Therefore, Boat speed = 4 km/h.
10. The sum of two numbers is 25 and their difference is 13. Find the numbers.
Answer: 19 and 6
Explanation: Let numbers be x and y. x + y = 25, x – y = 13. Adding both equations: 2x = 38, x=19. Then, 19 + y = 25, y=6.

- A person walks 6 km north, then 8 km east. Find the shortest distance from the starting point?
- Answer: 10 km
- Explanation: This forms a right-angled triangle. Shortest distance = Hypotenuse = √(6² + 8²) = √(36+64) = √100 = 10 km.
- Find the odd one out: 2, 6, 12, 20, 30, 42, 56, 70, 90?
- Answer: 90
- Explanation: The pattern is n×(n+1): 1×2=2, 2×3=6, 3×4=12, 4×5=20, 5×6=30, 6×7=42, 7×8=56, 8×9=72 (but it’s 70), 9×10=90. So, 70 is the true odd one as it breaks the pattern.
- Pointing to a man, a woman said, “His brother’s father is the only son of my grandfather.” How is the woman related to the man?
- Answer: Sister
- Explanation: “His brother’s father” is the man’s father. “The only son of my grandfather” is the woman’s father. So, the man’s father and the woman’s father are the same person. Therefore, they are brother and sister.
- In a row of girls, Priya is 10th from the left and Rekha is 17th from the right. If they interchange their positions, Priya becomes 15th from the left. How many girls are there in the row?
- Answer: 31
- Explanation: After interchange, Priya’s new position is 15th from left, which was originally Rekha’s position. So, Rekha’s original position from left is 15th. Rekha’s original position from right is 17th. Total girls = (Position from Left + Position from Right) – 1 = (15 + 17) – 1 = 31.
- Count the number of triangles in the given figure?(Note: As no figure was provided, this is a common question format.)
- Answer: (Answer would depend on the specific figure provided.)
- If ‘A + B’ means A is the brother of B, ‘A × B’ means A is the father of B, then what does ‘P × Q + R’ mean?
- Answer: P is the father of Q, and Q is the brother of R.
- Explanation: P × Q: P is father of Q. Q + R: Q is brother of R. So, P is the father of both Q and R.
- Which number will replace the question mark? 4, 7, 12, 19, 28, ?
- Answer: 39
- Explanation: The pattern is: +3, +5, +7, +9, +11. So, 28 + 11 = 39.
