Reasoning and computer awareness

20 AIIMS NORCET (Nursing Officer) practice questions on Reasoning and computer awareness, part of General Knowledge and Aptitude. The first 20 are below; the first 5 with answers and explanations (tap Show answer after you have chosen), the rest in Learn with a free account.

  1. Question 1 · Medium

    In a certain code, NURSE is written as OVSTF. How is DOCTOR written in that code?

    1. AFQEVQT
    2. BEPDUPR
    3. CCNBSNQ
    4. DEPDUPS
    Show answer

    Answer: D · EPDUPS

    Each letter of NURSE moves one place forward: N-O, U-V, R-S, S-T, E-F. Applying the same rule to DOCTOR gives D-E, O-P, C-D, T-U, O-P, R-S, which is EPDUPS. The rule must be checked on every letter of the example before it is applied. Coding questions often use a fixed shift like this.

    • A: FQEVQT shifts each letter two places forward.
    • B: EPDUPR leaves the last letter unchanged.
    • C: CNBSNQ shifts each letter one place backward.

  2. Question 2 · Medium

    Pointing to a woman in a photograph, Ravi says, "She is the daughter of my grandfather's only son." How is the woman related to Ravi?

    1. ACousin
    2. BAunt
    3. CNiece
    4. DSister
    Show answer

    Answer: D · Sister

    Ravi's grandfather's only son must be Ravi's father. The daughter of Ravi's father is Ravi's sister. The word 'only' rules out an uncle, which removes the cousin option. Blood relation questions are solved by replacing each phrase with a single relation, starting from the speaker.

    • A: A cousin would need the grandfather to have another son, which 'only son' excludes.
    • B: An aunt is the father's sister, the grandfather's daughter, not his son's daughter.
    • C: A niece is a sibling's daughter, one generation below Ravi.

  3. Question 3 · Medium

    In MS Excel, cell D2 contains the formula =$B$2*C2. If this formula is copied to cell D3, it becomes:

    1. A=$B$2*C2
    2. B=B3*C3
    3. C=$B$3*C3
    4. D=$B$2*C3
    Show answer

    Answer: D · =$B$2*C3

    The dollar signs make $B$2 an absolute reference, so it stays fixed wherever the formula is copied. C2 is a relative reference and moves with the formula, so one row down it becomes C3. The result is =$B$2*C3. Absolute references are used for a fixed value, such as a rate or a conversion factor, applied to a whole column.

    • A: C2 is relative, so it does not stay the same when copied down a row.
    • B: B3 ignores the dollar signs that lock the reference to B2.
    • C: $B$3 would require the row of the absolute reference to change, which the $ before 2 prevents.

  4. Question 4 · Medium

    A ward sister emails a duty roster to all staff and wants the nursing superintendent to get a copy without the staff seeing her address. In which field should the superintendent's address go?

    1. AReply-To
    2. BTo
    3. CBcc
    4. DCc
    Show answer

    Answer: C · Bcc

    Bcc (blind carbon copy) sends a copy to a recipient whose address is hidden from everyone else. Addresses in To and Cc are visible to all recipients. Bcc is also used for group emails to protect recipients' addresses. Reply-To only sets where replies are sent.

    • A: Reply-To changes the address that receives replies; it does not send a copy.
    • B: To lists the main recipients, and their addresses are visible to everyone.
    • D: Cc sends a copy, but the address is visible to all recipients.

  5. Question 5 · Medium

    Choose the number that completes the analogy 4 : 64 :: 6 : ?

    1. A216
    2. B66
    3. C96
    4. D36
    Show answer

    Answer: A · 216

    64 is 4 cubed (4 x 4 x 4), so the relation is a number and its cube. The cube of 6 is 6 x 6 x 6 = 216. Checking the relation by more than one route helps: 64 is also 4 x 16, but only cubing gives a rule that is natural for both pairs. Analogy rules should be the simplest rule that fits.

    • B: 66 adds 2 to 64 because 6 is 2 more than 4.
    • C: 96 multiplies 6 by 16, copying a factor from the first pair instead of the rule.
    • D: 36 is 6 squared, a different power from the one in the first pair.

  6. Question 6 · Medium
