Download Class 9 Math – Miscellaneous Exercise 3 Notes – Sets & Relations (FBISE SLO‑Based 2025)

The Miscellaneous Exercise 3 is where all the individual skills from Exercises 3.1–3.4 unite. You’ll decode complex statements, translate everyday language into symbolic notation, and solve layered questions that mix union, intersection, complement and number‑of‑elements techniques in a single scenario. This is exactly how exam paper setters test higher‑order thinking, so practising here means walking into the annual paper with your last‑minute nerves calmed. While our guide is tuned to the FBISE 2025 SLOs, it also mirrors the patterns used by BIE Karachi and BISE Multan boards, letting you revise once and score everywhere.

Inside you’ll find:

• Quick recaps of each exercise’s core theorem.
• Fifteen multi‑concept problems fully solved.
• Smart hints that point out common traps examiners love to set.
• Self‑assessment grid to rate your readiness before moving to Unit 4.
