AP Police PC 2021 PYQ-pattern questions

Showing 10 of the 15 PYQ-pattern questions in this set — freshly worded in that year's pattern, not the original questions. Answers and solutions open under each question.

1. Q1 · Direction and Distance

   Ramesh walks 5 km towards North, then turns right and walks 3 km. He then turns right again and walks 5 km. How far is he from the starting point?

   • A. 3 km
   • B. 5 km
   • C. 8 km
   • D. 13 km
   Answer and solution

   Answer: A

   After the movements, Ramesh is 3 km East of his starting point, forming a rectangular path.

2. Q2 · Series

   Find the next term in the series: A, C, F, J, O, ?

   • A. T
   • B. U
   • C. V
   • D. W
   Answer and solution

   Answer: B

   The pattern increases by 2, 3, 4, 5, 6... positions in the alphabet (A+2=C, C+3=F, F+4=J, J+5=O, O+6=U).

3. Q3 · Non-Verbal Reasoning

   In a sequence of figures, a triangle rotates 45° clockwise at each step. If the triangle is pointing upwards initially, in which direction will it point after 3 steps?

   • A. Upward-right diagonal
   • B. Downward
   • C. Right
   • D. Downward-right diagonal
   Answer and solution

   Answer: D

   Initial position is upward (0°). After 1 step: 45° (upward-right diagonal). After 2 steps: 90° (right). After 3 steps: 135° (downward-right diagonal). Hence, the answer is downward-right diagonal.

4. Q4 · Simplification

   Find the value of: (625)^(1/4) + (256)^(1/4)

   • A. 7
   • B. 9
   • C. 11
   • D. 13
   Answer and solution

   Answer: B

   The fourth root of 625 is 5 (since 5^4 = 625). The fourth root of 256 is 4 (since 4^4 = 256). Therefore, 5 + 4 = 9.

5. Q5 · Simple Interest

   Find the simple interest on ₹8000 at 5% per annum for 3 years.

   • A. ₹1000
   • B. ₹1100
   • C. ₹1200
   • D. ₹1300
   Answer and solution

   Answer: C

   Simple Interest = (P × R × T)/100 = (8000 × 5 × 3)/100 = ₹1200.

6. Q6 · Profit and Loss

   An article is sold for ₹540 at a loss of 10%. What was the cost price?

   • A. ₹580
   • B. ₹590
   • C. ₹600
   • D. ₹610
   Answer and solution

   Answer: C

   If CP is x, then 90% of x = 540, so x = (540 × 100)/90 = ₹600.

7. Q7 · Data Interpretation

   The following data shows the number of students enrolled in different courses: Engineering-320, Medicine-180, Commerce-240, Arts-160. What percentage of students enrolled in Commerce?

   • A. 26.67%
   • B. 28.50%
   • C. 25.00%
   • D. 30.00%
   Answer and solution

   Answer: A

   Total students = 320+180+240+160 = 900. Commerce percentage = (240/900)×100 = 26.67%.

8. Q8 · Mensuration

   The curved surface area of a cylinder is 1,760 sq cm and its height is 20 cm. What is the radius of the cylinder? (Use π = 22/7)

   • A. 12 cm
   • B. 14 cm
   • C. 16 cm
   • D. 18 cm
   Answer and solution

   Answer: B

   Curved surface area = 2πrh. So 1760 = 2×(22/7)×r×20. Solving: r = (1760×7)/(2×22×20) = 12320/880 = 14 cm.

9. Q9 · Physics

   A car moving at 20 m/s applies brakes and comes to rest in 4 seconds. What is its deceleration?

   • A. 4 m/s²
   • B. 5 m/s²
   • C. 8 m/s²
   • D. 10 m/s²
   Answer and solution

   Answer: B

   Using v = u + at, where final velocity v=0, initial velocity u=20 m/s, time t=4s: 0 = 20 + a(4), so a = -5 m/s². Deceleration is 5 m/s².

10. Q10 · Biology

    The process by which green plants prepare their own food using sunlight, carbon dioxide, and water is called:

    • A. Respiration
    • B. Photosynthesis
    • C. Transpiration
    • D. Digestion
    Answer and solution

    Answer: B

    Photosynthesis is the process by which green plants use chlorophyll, sunlight, CO₂, and water to produce glucose and oxygen.
