Person A is 3 years younger than B, and person C is 2 years older than A. What is B’s relation to C (who is older/younger and by how much)?

Introduction / Context:Chain simple differences to compare two people indirectly via a third person.

Given Data / Assumptions:

• A = B − 3
• C = A + 2

Concept / Approach:Express C in terms of B and then compare B and C directly.

Step-by-Step Solution:

Verification / Alternative check:Pick B = 10 ⇒ A = 7 ⇒ C = 9 ⇒ B is 1 year older than C, consistent.

Why Other Options Are Wrong:Two years older/younger or one year younger contradict C = B − 1.

Common Pitfalls:Reversing who is older due to sign mistakes in the differences.

Final Answer:One year older.
