  1. If all Bloops are Razzles and all Razzles are Lazzles, which statement must be true?

    Answer: All Bloops are Lazzles

    By transitivity: Bloops → Razzles → Lazzles, so all Bloops are Lazzles.

  2. A shopkeeper marks goods 40% above cost price and gives a 20% discount. His profit percentage is:

    Answer: 12%

    SP = 1.4 × 0.8 × CP = 1.12 CP, giving a 12% profit.

  3. Find the missing number: 4, 9, 25, 49, 121, __

    Answer: 169

    The series is squares of prime numbers (2², 3², 5², 7², 11²), so next is 13² = 169.

  4. Two numbers are in the ratio 3:5. If 8 is added to each, the ratio becomes 2:3. What is the smaller number?

    Answer: 24

    Let numbers be 3x and 5x; (3x+8)/(5x+8) = 2/3 → x = 8; smaller = 24.

  5. A person walks at 4 km/h for the first half of a journey and at 6 km/h for the second half. What is the average speed for the entire journey?

    Answer: 4.8 km/h

    Average speed for equal distances = 2×4×6/(4+6) = 48/10 = 4.8 km/h.

  6. In a class, 60% of students passed Math, 70% passed Science, and 40% passed both. What percentage failed both?

    Answer: 10%

    Passed at least one = 60+70−40 = 90%; failed both = 100−90 = 10%.

  7. Statements: All pens are books. Some books are pencils. Conclusion I: Some pens are pencils. Conclusion II: Some pencils are pens. Which is correct?
