Sample Management Service Officers' Service Exam Practice Questions

Try these sample questions to review concepts for the Management Service Officers' Service Exam exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Consider the following numerical sequence: 4, 9, 19, 39, 79, ____. Which number correctly completes the series?
A.149
B.159
C.168
D.179
Explanation: Each successive term is obtained by multiplying the previous number by 2 and adding 1: (4 × 2) + 1 = 9; (9 × 2) + 1 = 19; (19 × 2) + 1 = 39; (39 × 2) + 1 = 79. Following this rule, the next term is (79 × 2) + 1 = 158 + 1 = 159.
2Complete the verbal analogy based on standard public sector registry practice: General Ledger is to Financial Accounts as Logbook is to:
A.Official Vehicle Movements
B.Staff Attendance Records
C.Incoming Public Petitions
D.Annual Inventory Verifications
Explanation: In Sri Lanka public sector office administration, a General Ledger is the primary record for tracking financial transactions and account balances, whereas a Vehicle Logbook (running chart) is the mandatory official register used to track government vehicle journeys, fuel issues, and mileage. Staff attendance is recorded in the Attendance Register or electronic clock system, petitions are logged in the Petitions Register, and inventory verifications are recorded in Board of Survey schedules.
3In a Divisional Secretariat, 3 Management Assistants can verify and index 90 public assistance application files in 6 hours. Working at the same constant rate, how many application files can 5 Management Assistants verify and index in 8 hours?
A.160 files
B.180 files
C.200 files
D.240 files
Explanation: First, calculate the individual filing rate: 3 assistants working 6 hours provide 18 assistant-hours to process 90 files, which equals 90 / 18 = 5 files per assistant per hour. Next, 5 assistants working for 8 hours provide 5 × 8 = 40 assistant-hours. Multiplying by the individual rate gives 40 × 5 = 200 application files.
4Read the following statements carefully: 1. All Establishments Circulars are mandatory administrative directives. 2. Some administrative directives require concurrence from the General Treasury. Which of the following conclusions logically and necessarily follows from these premises?
A.All Establishments Circulars require prior concurrence from the General Treasury.
B.No administrative directive can be issued without General Treasury approval.
C.Some mandatory administrative directives may require concurrence from the General Treasury.
D.Only financial circulars are classified as mandatory administrative directives.
Explanation: Since all Establishments Circulars are mandatory administrative directives, the set of Establishments Circulars is a subset of mandatory administrative directives. Because some administrative directives require General Treasury concurrence, it logically follows that some mandatory administrative directives may require concurrence from the General Treasury. We cannot deduce that all Establishments Circulars require Treasury concurrence, nor that only financial circulars are mandatory.
5Determine the number that correctly completes the progressive mathematical series: 3, 8, 27, 112, 565, ____.
A.2,825
B.3,396
C.3,955
D.4,520
Explanation: The series follows the progressive rule: multiply by n and add n, starting with n = 2. Specifically: (3 × 2) + 2 = 8; (8 × 3) + 3 = 27; (27 × 4) + 4 = 112; (112 × 5) + 5 = 565. To find the next term, multiply by 6 and add 6: (565 × 6) + 6 = 3,390 + 6 = 3,396.
6Identify the odd one out among the following public finance designations based on constitutional status and reporting line in Sri Lanka:
A.Chief Accounting Officer
B.Accounting Officer
C.Auditor General
D.Revenue Accounting Officer
Explanation: Under the Constitution of Sri Lanka and the Financial Regulations (FR), the Auditor General is an independent constitutional officer (Article 153) appointed by the President subject to constitutional council approval, reporting directly to Parliament and external to departmental administration. In contrast, the Chief Accounting Officer (Ministry Secretary), Accounting Officer (Head of Department), and Revenue Accounting Officer are executive officers within the administration appointed under Financial Regulations to execute and account for public revenues and expenditures.
7A provincial department received an annual budgetary allocation of Rs. 4,800,000 for office consumables. In the first quarter, 35% of the total allocation was expended. In the second quarter, 40% of the remaining balance was expended. What is the unexpended balance remaining at the beginning of the third quarter?
A.Rs. 1,248,000
B.Rs. 1,680,000
C.Rs. 1,872,000
D.Rs. 2,160,000
Explanation: Initial allocation = Rs. 4,800,000. Q1 expenditure = 35% of 4,800,000 = Rs. 1,680,000. Balance after Q1 = 4,800,000 - 1,680,000 = Rs. 3,120,000. Q2 expenditure is 40% of the remaining balance = 0.40 × 3,120,000 = Rs. 1,248,000. Balance remaining at the start of Q3 = 3,120,000 - 1,248,000 = Rs. 1,872,000.
8An administrative officer departs from the District Secretariat and travels 4 km North to inspect a branch office. She then turns right and travels 3 km East to inspect a training centre. From there, she turns right again and travels 8 km South to an agrarian service centre. What is her direct straight-line distance from the starting point at the District Secretariat?
A.5 km
B.7 km
C.9 km
D.11 km
Explanation: Calculate net displacement in cardinal directions: North-South displacement is 4 km North - 8 km South = 4 km South. East-West displacement is 3 km East. Applying the Pythagorean theorem for the right-angled triangle formed: Direct distance = √(3² + 4²) = √(9 + 16) = √25 = 5 km.
9In a data accuracy verification exercise on public service pension files, which of the following pairs contains an exact match between the Original and the Duplicate without any typographical error?
A.Original: PEN-WP/KL-892405-X7 || Duplicate: PEN-WP/KL-892405-X7
B.Original: EST/2026/PROV-04812-B || Duplicate: EST/2026/PROV-04821-B
C.Original: NIC-198854201389-V || Duplicate: NIC-198854201380-V
D.Original: DS/DIV-GAM/ACC-73918 || Duplicate: DS/DIV-GAM/AAC-73918
Explanation: Pair A is an exact character-by-character match: PEN-WP/KL-892405-X7 is identical in both strings. In Pair B, 04812 is transposed to 04821. In Pair C, the terminal digit 9 is replaced by 0. In Pair D, the branch code ACC is misspelled as AAC.
10Three administrative branches—Establishments, Accounts, and Planning—agree to share the procurement cost of a central heavy-duty network scanner priced at Rs. 240,000 in the ratio 3 : 4 : 5 respectively. How much must the Accounts branch contribute towards the purchase?
A.Rs. 60,000
B.Rs. 80,000
C.Rs. 100,000
D.Rs. 120,000
Explanation: First, sum the ratio components: 3 + 4 + 5 = 12 total parts. The monetary value of one part is Rs. 240,000 / 12 = Rs. 20,000. Because the Accounts branch is responsible for 4 parts of the ratio, its share is 4 × Rs. 20,000 = Rs. 80,000.

Management Service Officers' Service Exam: Suggested Study Strategy

1Split your preparation 50/50. The two papers carry equal marks and you must clear 40% in each, so a candidate who is strong only at arithmetic and reasoning will still fail. Draft one official letter and one summary every week in the medium you will sit the paper in.
2Drill the Language Proficiency task types by name: essay on a set topic, drafting a given letter, comprehension of a passage, summarising a passage, expressing the idea of several given sentences in one sentence, presenting given data as a graph, spelling and simple grammar. Each is listed in the Gazette syllabus, so practise all of them rather than only essays.
3Train for speed on the Aptitude paper: 50 questions in 60 minutes leaves about 70 seconds per item. Practise percentages, ratios, averages, work-and-rate and time-and-distance mentally, and learn to skip and return rather than stalling on one puzzle.
4Remember the 50% aggregate rule. Because the total-mark threshold sits above the per-paper threshold, aim for a comfortable margin in your stronger paper instead of settling for a bare 40% pass in each.

Frequently Asked Questions

It is the national open competitive examination conducted by the Commissioner General of Examinations on behalf of the Director General of Combined Services, Ministry of Public Administration, Provincial Councils and Local Government. It recruits Sri Lankan citizens into Grade III of the Management Service Officers' Service — the service formerly named the Public Management Assistants' Service, whose Service Minute was published in Gazette Extraordinary No. 1840/34 of 11 December 2013.

What is the examination structure, duration and passing standard?

The 2026 Gazette sets two written papers: Paper 01 Language Proficiency (100 marks, 2 1/2 hours) covering expression, comprehension, spelling, essay, drafting a given letter, making graphs from given data, summarising passages, condensing several sentences into one and simple grammar; and Paper 02 Aptitude (100 marks, 1 hour) consisting of 50 multiple-choice and short-answer questions on skill at numbers, critical reasoning and general intelligence.

What are the eligibility requirements and the examination fee?

Applicants must be Sri Lankan citizens aged not less than 18 and not more than 30 years on the closing date of applications, must have passed the GCE Ordinary Level in six subjects with credit passes for four subjects including Language (Sinhala/Tamil/English) and Mathematics at one sitting, and must have passed all subjects at the GCE Advanced Level at one sitting (excluding the General Paper and General English). The examination fee is Rs. 600.00, payable only through the online payment channels named in the Gazette. Three per cent of the vacancies are reserved for persons with disabilities.

How does this OpenExamPrep practice bank support candidate preparation?

This is independent practice by OpenExamPrep for the Management Service Officers' Service Grade III examination and the topics it covers. It is not an official paper, a format simulation, or a publication endorsed by the Department of Examinations or the Ministry of Public Administration. The official examination is sat in Sinhala, Tamil or English and its Language Proficiency paper is answered in continuous writing; this bank is an English-language multiple-choice study adaptation of that paper's underlying comprehension, summarising, letter-drafting and grammar skills, alongside Aptitude practice that follows the official multiple-choice format more closely. Writing practice in your chosen medium is still required and cannot be replaced by multiple-choice questions.
