  1. 1 1. Which number comes next in the sequence? 3, 6, 11, 18, ...

    1. 25
    2. 24
    3. 27
    Correct!
    Wrong!

    Explanation

    The differences between the numbers are increasing by 2 each time (3 to 6 is +3, 6 to 11 is +5, 11 to 18 is +7). The next difference will be +9, so 18 + 9 = 27.

  2. 2 If all cats are animals and some animals are dogs, can we say that some cats are definitely dogs?

    1. yes
    2. no
    3. maybe
    Correct!

    Explanation

    The statement does not provide any direct connection between cats and dogs. Therefore, the answer is B) No.

  3. 3 What is the odd one out? Circle, Triangle, Square, Rectangle

    1. Circle
    2. Triangle
    3. Square
    Correct!

  4. 4 4. If a car travels 120 miles in 2 hours, what is its average speed?

    1. 50 mph
    2. 60 mph
    3. 70 mph
    Correct!
    Wrong!

    Explanation:

     Average speed is calculated as Distance / Time. Therefore, 120 miles / 2 hours = 60 mph.

  5. 5 Find the missing number in this pattern: 2, 4, 8, 14, ...

    1. 20
    2. 22
    3. 24
    Correct!
    Wrong!

    Explanation:

     The pattern increases by 2, 4, 6, and 8, respectively. The next increment is 10, so 14 + 10 = 24.

  6. 6 In a right triangle, if one angle is 30 degrees, what is the other non-right angle?

    1. 45 degrees
    2. 60 degrees
    3. 90 degrees
    Correct!
    Wrong!

    Explanation:

     The sum of angles in a triangle is 180 degrees. In a right triangle, one angle is 90 degrees, so the other angle must be 180 - 90 - 30 = 60 degrees.

  7. 7 If 5x + 3 = 23, what is the value of x?

    1. 4
    2. 5
    3. 6
    Correct!
    Wrong!

    Explanation:

    To solve for x, first subtract 3 from both sides: 5x = 20. Then divide by 5: x = 4.

    1. Clear
    2. Opaque

    1. 200 km
    2. 240 km
    3. 280 km
    Correct!
    Wrong!

    Explanation:

    Distance = Speed × Time. So, 80 km/h × 3 hours = 240 km.

  10. 10 Which of the following is a prime number?

    1. 9
    2. 11
    3. 15
    Correct!
    Wrong!
