29. Full-Length Mock Test 1 — AP SI/Constable Prelims Pattern (100 MCQs)
This mock test follows the general AP SI/Constable Preliminary pattern discussed in Chapter 28: a General Studies section of 50 questions covering history, polity, geography, economy, science, general current-affairs-style awareness, and Andhra Pradesh-specific content, followed by an Arithmetic section of 30 questions and a Reasoning section of 20 questions. Attempt this paper under timed conditions for a realistic self-assessment. Each question carries four options; the correct answer is marked at the end of each question.
Instructions Before You Begin
Simulate real exam conditions as closely as possible. Set a timer for a total of 100 to 120 minutes depending on the specific time allowance in your actual notification, and do not pause the clock once you begin. Attempt the General Studies section first, followed by Arithmetic, followed by Reasoning, or follow whatever section order your own notification specifies — the important discipline is completing all three sections inside a single continuous timed block rather than spreading the attempt across multiple sittings, since fatigue and time pressure late in the paper are themselves part of what this mock is meant to simulate. Mark your answer choice for every question as you go, including a best guess on questions you are unsure of, unless your actual exam's negative marking scheme makes guessing on fully unfamiliar questions a poor strategy — refer back to the negative-marking discussion in Chapter 28 before deciding your own guessing policy. Once the timer ends, stop immediately, even if questions remain unattempted, since an honest sense of your real completion rate under time pressure is one of the most valuable outputs of this exercise.
After completing the paper, score yourself against the answer key embedded in each question below, then move to the worked-explanations section at the end of this chapter, which covers the arithmetic and reasoning questions most likely to have caused difficulty. Log your section-wise accuracy and completion rate somewhere you will return to — ideally alongside your results from Mock Test 2 in the next chapter — so that you can track whether your pacing and accuracy are improving across attempts rather than judging each mock in isolation.

Worked Explanations — Arithmetic Section
The following brief explanations cover the arithmetic questions most likely to trip up candidates under time pressure; use them to check your method, not just your final answer.
- Q52: If 120% of x = 180, then x = 180 / 1.2 = 150.
- Q54: Profit = 920 - 800 = 120; profit percent = 120/800 x 100 = 15%.
- Q57: Men and days are inversely proportional: 5 x 12 = 10 x d, so d = 6 days.
- Q59: CI = 2000 x (1.1)^2 - 2000 = 2420 - 2000 = 420.
- Q62: Selling price of 16 articles = cost price of 20 articles, so profit on 16 articles = cost of 4 articles; profit percent = 4/16 x 100 = 25%.
- Q63: Combined rate = 1/20 + 1/30 = 3/60 + 2/60 = 5/60 = 1/12, so together they take 12 minutes.
- Q64: Doubling means SI equals the principal itself; using SI = PRT/100, P = P x R x 8/100, giving R = 100/8 = 12.5%.
- Q68: Average speed for equal distances at two different speeds = 2ab/(a+b) = 2x60x40/100 = 48 km/h.
- Q71: Let the number be n; n - 0.6n = 24, so 0.4n = 24, n = 60.
- Q72: Combined rate = 1/10 + 1/15 = 3/30 + 2/30 = 5/30 = 1/6, so together they take 6 days.
- Q76: C's share = 6300 x 4/9 = 2800 (since the ratio parts sum to 2+3+4 = 9).
- Q77: Downstream speed = 30/2 = 15 km/h; upstream speed = 30/3 = 10 km/h; speed in still water = (15+10)/2 = 12.5 km/h.
- Q79: Let father's age = 3s and son's age = s. After 12 years: 3s+12 = 2(s+12), giving 3s+12 = 2s+24, so s = 12.
- Q80: Net filling rate = 1/6 - 1/8 = 4/24 - 3/24 = 1/24, so the cistern fills in 24 hours.
Worked Explanations — Reasoning Section
- Q81: The differences between consecutive terms are 4, 6, 8, 10, 12 — an increasing even sequence — so the next term is 30 + 12 = 42.
- Q82: Each letter of the code is shifted forward by one position in the alphabet: C→D, A→B, T→U; applying the same rule to D, O, G gives E, P, H.
- Q83: The man's grandfather's only son is the man's own father; the father's daughter is therefore the man's sister.
- Q84: Walking 5 km north, then 3 km east, then 5 km south returns the walker to the same latitude as the start, leaving only the 3 km eastward displacement.
- Q89: The gaps between letters increase by one each time (2, 3, 4, 5), so after O (gap 5) comes a gap of 6, landing on U.
- Q90: The sequence is the squares of consecutive integers (2² to 7²); the missing term is 6² = 36.
- Q91: Each direction is rotated by a fixed 225-degree shift; applying that same rotation to South yields North-West.
- Q94: Each term doubles the previous one, so 56 x 2 = 112.
- Q97: At 3:15, the hour hand has moved 7.5 degrees past the 3 o'clock mark (0.5 degrees per minute), while the minute hand sits exactly at the 15-minute mark, giving a 7.5-degree gap.
- Q100: The differences between consecutive terms rise by 2 each time (5, 7, 9, 11, 13), so the next term is 35 + 13 = 48.
How to Use These Solutions
Do not read these worked explanations before attempting the paper — they are designed for the review phase only. After completing the full 100-question paper under timed conditions, mark your answers against the answer key embedded in each question, then work through the explanations above for every arithmetic and reasoning question you got wrong. For the General Studies section, the correct option is stated directly after each question; where you got a General Studies question wrong, cross-reference the relevant fact against the subject-matter chapters earlier in this book rather than treating the isolated fact in this mock as your only exposure to it. This layered review — attempt, self-check, explanation, cross-reference — is considerably more effective at raising your actual exam-day score than simply noting your total and moving on to the next mock test.
Self-Assessment Guide
| Section | Questions | Suggested Time Budget | What Weak Performance Here Usually Indicates |
|---|---|---|---|
| General Studies | 50 | Roughly 40-45 minutes | Content gaps in specific sub-topics — revisit the relevant subject chapters rather than re-reading this mock alone |
| Arithmetic | 30 | Roughly 35-40 minutes | Either conceptual gaps in a specific question type (percentages, time-and-work, ratios) or a pure speed problem — check whether errors or blanks dominate |
| Reasoning | 20 | Roughly 20-25 minutes | Format unfamiliarity — reasoning errors usually cluster around one or two specific formats (blood relations, coding-decoding, series) rather than being spread evenly |
Once you have completed and reviewed this mock, proceed to Mock Test 2 in the next chapter, ideally after at least one full day of targeted revision on whichever weak areas this attempt exposed, so that the second mock genuinely tests improvement rather than repeating the same gaps.
