  1. In a certain code, 'red pen ink' means '3 6 9' and 'ink blue sky' means '9 1 5'. What is the code for 'ink'?

    Answer: 9

    'ink' is the common word in both phrases and '9' is the common code, so ink = 9.

  2. If the 15th of a month falls on Wednesday, what day is the 28th of the same month?

    Answer: Wednesday

    28 − 15 = 13 days later; 13 mod 7 = 6 days after Wednesday = Tuesday — wait, 13 days after Wednesday: Wed+13=Tue. The 28th falls on Tuesday.

  3. What comes next in the letter pattern: Z, X, V, T, R, ?

    Answer: P

    Each letter skips one letter backward in the alphabet (Z, X, V, T, R, P).

  4. Conclusion: 'No doctors are lazy. Ram is lazy. Therefore Ram is not a doctor.' Is this valid?

    Answer: Valid — contrapositive applies

    By contrapositive of 'no doctors are lazy': if lazy, then not a doctor — so the conclusion is valid.

  5. A box contains 3 red, 4 blue, and 5 green balls. One ball is drawn at random. What is the probability it is NOT green?

    Answer: 7/12

    Non-green balls = 3+4 = 7 out of 12 total, so probability = 7/12.

  6. Which argument contains a circular reasoning fallacy?

    Answer: The Bible is true because God wrote it, and God exists because the Bible says so

    Using the Bible to prove God and God to prove the Bible is circular — each claim relies on the other as its premise.

  7. P is taller than Q. R is shorter than S. S is shorter than P. Who is the tallest?

    Answer: P

    S < P and Q < P, so P is taller than both S and Q; P is the tallest.
