1If each letter of the alphabet is assigned a value based on its position in the alphabet using the formula Value = 2n - 1 (where n is the position, i.e., A=1, B=3, C=5...), what is the sum of the letters in the abbreviation 'KDU'?

A.65

B.69

C.72

D.75

Explanation: K is the 11th letter, so its value is 2(11) - 1 = 21. D is the 4th letter, so its value is 2(4) - 1 = 7. U is the 21st letter, so its value is 2(21) - 1 = 41. Sum = 21 + 7 + 41 = 69.

2Look at this series: 2, 5, 11, 23, 47, ... What number should come next?

A.93

B.95

C.97

D.99

Explanation: This is an arithmetic progression where each term is twice the previous term plus one: (2 * 2) + 1 = 5; (5 * 2) + 1 = 11; (11 * 2) + 1 = 23; (23 * 2) + 1 = 47. The next term is (47 * 2) + 1 = 95.

3If in a certain code, 'ARMY' is written as 'BSNZ', how is the word 'NAVY' written in that code?

A.OBWZ

B.OCXA

C.PBWZ

D.OBYA

Explanation: The pattern involves shifting each letter forward by 1 in alphabetical order: A -> B, R -> S, M -> N, and Y -> Z. Applying the same rule to NAVY: N (+1) -> O, A (+1) -> B, V (+1) -> W, and Y (+1) -> Z. Thus, NAVY is coded as OBWZ.

4Which word completes the logical analogy? Book is to Author as Statue is to _______.

A.Mason

B.Painter

C.Sculptor

D.Architect

Explanation: An author is the creator of a book. Similarly, a sculptor is the creator of a statue.

5A cadet walks 10 km South from the barracks, turns right and walks 5 km, then turns left and walks 10 km, and finally turns right and walks 5 km. In which direction is he now with respect to his starting point?

A.South

B.West

C.South-West

D.North-West

Explanation: Let starting point be (0,0). Walking 10 km South leads to (0, -10). Turning right (facing West) and walking 5 km leads to (-5, -10). Turning left (facing South) and walking 10 km leads to (-5, -20). Turning right (facing West) and walking 5 km leads to (-10, -20). The final position (-10, -20) lies to the South-West of the starting point (0,0).

6Pointing to a photograph, a gentleman said, 'I have no brother or sister, but that man's father is my father's son.' Whose photograph was it?

A.His father's

B.His son's

C.His uncle's

D.His nephew's

Explanation: Since the speaker has no brother or sister, 'my father's son' must be the speaker himself. The statement 'that man's father is my father's son' therefore simplifies to 'that man's father is myself'. Thus, the photograph is of the gentleman's son.

7Which of the following spatial concepts best represents the logical relationship between the classes: 'Sri Lanka Army', 'Sri Lanka Navy', and 'Sri Lanka Air Force'?

A.Three intersecting circles showing overlapping membership

B.Three separate, mutually exclusive circles

C.One large circle enclosing two smaller circles

D.Two concentric circles and one separate circle

Explanation: The Sri Lanka Army, Navy, and Air Force are three distinct and mutually exclusive branches of the armed forces with separate structures and personnel. Therefore, they are represented by three separate, non-overlapping circles in a Venn diagram.

8If the day after tomorrow is Sunday, what day of the week was the day before yesterday?

A.Monday

B.Tuesday

C.Wednesday

D.Thursday

Explanation: If the day after tomorrow is Sunday, then tomorrow is Saturday, and today is Friday. Yesterday was Thursday, and the day before yesterday was Wednesday.

9Find the odd one out among the following Sri Lankan cities based on the presence of a primary tri-forces officer cadet training academy (excluding KDU):

A.Diyatalawa

B.Trincomalee

C.China Bay

D.Kandy

Explanation: Diyatalawa hosts the Sri Lanka Military Academy (Army), Trincomalee hosts the Naval and Maritime Academy (Navy), and China Bay (Trincomalee) hosts the Sri Lanka Air Force Academy. Kandy does not host a primary military officer training academy of the tri-forces.

10Statements: All officer cadets are disciplined. All disciplined individuals make good leaders. Conclusions: I. All officer cadets make good leaders. II. Some disciplined individuals are officer cadets. Which of the conclusions logically follow(s)?

A.Only conclusion I follows

B.Only conclusion II follows

C.Both conclusions I and II follow

D.Neither conclusion I nor II follows

Explanation: Based on the statements: 'All officer cadets are disciplined' (A in B) and 'All disciplined individuals make good leaders' (B in C). Thus, all officer cadets make good leaders (A in C), so Conclusion I follows. Also, since all officer cadets are disciplined, there are disciplined individuals who are officer cadets, meaning Conclusion II ('Some disciplined individuals are officer cadets') also follows.
