Sample Questions

Question 1:

Statement: In a group of five friends—A, B, C, D, and E—each plays a different sport: cricket, football, tennis, badminton, and hockey. A does not play cricket or hockey. B plays football. C does not play tennis or badminton. D plays hockey.

Who plays cricket?

Solution:

• B plays football.
• D plays hockey.
• A does not play cricket or hockey, leaving tennis or badminton.
• C does not play tennis or badminton, leaving cricket or football. Since B plays football, C must play cricket.
• E, by elimination, plays the remaining sport.

Answer: C plays cricket.

Question 2:

Statement: A sequence of numbers is given: 2, 6, 12, 20, 30, ...

What is the next number in the sequence?

Solution:

• The pattern follows: $n^2 + n$, where $n$ is the position in the sequence.
  • 1st term: $1^2 + 1 = 2$
  • 2nd term: $2^2 + 2 = 6$
  • 3rd term: $3^2 + 3 = 12$
  • 4th term: $4^2 + 4 = 20$
  • 5th term: $5^2 + 5 = 30$
• 6th term: $6^2 + 6 = 36 + 6 = 42$

Answer: The next number is 42.
