Question Analysis:
This is a classic contrapositive transformation.
The main focus is reversing and negating the original conditional logically.

Key Concept Explanation:
For “If p → q”, the contrapositive is “If not q → not p”.
Original:
p: number is divisible by 6
q: number is divisible by 3
Contrapositive:
not q → not p
If not divisible by 3, then not divisible by 6

Step-by-Step Solution:
Identify q: “divisible by 3”
Negate: “not divisible by 3” → that’s your assumption
Show that a number not divisible by 3 can’t be divisible by 6 (since 6 = 2 × 3)
Therefore, contrapositive is proven

Option Analysis:
A. ❌ Original hypothesis, not contrapositive
B. ❌ Negation of w...
