  1. Question 1
    What does each picture in a pictograph represent?
    • A fixed number (correct answer)
    • Percentage
    • Sector
    • Angle
    Correct answer: A
    Pictographs use symbols to represent data, and each symbol stands for a specific, constant quantity, not a percentage, sector, or angle.
  2. Question 2
    A square number pattern is 1, 4, 9, 16… What is the 10th term?
    • 90
    • 91
    • 100 (correct answer)
    • 101
    Correct answer: C
    Identify the pattern in a sequence of square numbers and calculate a specific term within that sequence.
  3. Question 3
    What is the sum of the infinite geometric progression 1, 1/2, 1/4, 1/8,...?
    • 1.5
    • 1.75
    • 1.8
    • 2 (correct answer)
    Correct answer: D
    Master the formula for the sum of an infinite geometric series to solve problems like this common progression.
  4. Question 4
    20th term from the last term of the A.P. 3, 8, 13, …, 253 is:
    • 147
    • 151
    • 154
    • 158 (correct answer)
    Correct answer: D
    Find the 20th term from the end of an arithmetic progression (AP) by reversing the sequence or working backward from the last term.
  5. Question 5
    Which term of the AP: 4, 9, 14, 19, ... is 64?
    • 12th
    • 13th (correct answer)
    • 14th
    • 15th
    Correct answer: B
    This question tests the ability to find the 'n'-th term of an arithmetic progression (AP) using the standard formula. Solve for 'n' when the term value is given.
  6. Question 6
    The 10th term of the AP: 5, 8, 11, 14, … is
    • 32 (correct answer)
    • 35
    • 38
    • 185
    Correct answer: A
    Master arithmetic progression (AP) problems by identifying the first term and common difference to find any term using the formula an=a1+(n−1)da_n = a_1 + (n-1)d.
  7. Question 7
    If the 2nd term of a G.P. is 6 and the 4th term is 24, what is the common ratio?
    • 2 (correct answer)
    • √2
    • 3
    • 4
    Correct answer: A
    Calculate the common ratio of a geometric progression given two terms.
  8. Question 8
    Which of the following is an infinite set?
    • {2, 4, 6, 8}
    • Set of all prime numbers (correct answer)
    • Set of vowels in English
    • Set of months in a year
    Correct answer: B
    This question tests the fundamental understanding of finite vs. infinite sets, a core concept in basic mathematics crucial for various scientific disciplines.
