Data Sufficiency: Rank-Based Logic and Order

Learn core concepts, essential formulas, and attempt practice questions designed on the latest TCS NQT testing patterns.

Key Concepts & Formulas

  • 1Establish linear ranks equations.
  • 2Position formula: Total = (Rank from Top + Rank from Bottom) - 1.

TCS NQT Style Practice Questions

Practice Question 1

What is Ravi's rank? (1) He is 5th from the top. (2) He is 10th from the bottom.

A) Both together sufficient
B) 1 alone sufficient
C) 2 alone sufficient
D) Neither sufficient

Correct Answer: A) Both together sufficient

Step-by-step Solution: To find Ravi's exact rank or the total, we need both references. Total = 5 + 10 - 1 = 14. Hence, both statements together are sufficient.

Practice Question 2

Who is the tallest among A, B, C? (1) A is taller than B. (2) B is taller than C.

A) Both together sufficient
B) 1 alone sufficient
C) 2 alone sufficient
D) Neither sufficient

Correct Answer: A) Both together sufficient

Step-by-step Solution: Combining both statements: A > B and B > C => A > B > C. Therefore, A is the tallest. Both statements together are sufficient.

Study Pro-Tip

Do not assume values. Check if a single ordering chain can be established.
