L-28 | Circular Permutations | Table Arrangements, Necklaces, Mirror Images | JEE Mains & Advanced

Описание: Circular Permutations explained with Round Table Arrangements, Necklace Problems, Mirror Images, Rotational Equivalence, and Advanced JEE Constraints.
Includes seating, beads, identical chairs, flipping cases, PM fixed seat, boys-girls alternate, groups together, and complete JEE Mains + Advanced questions.
Full theory + visualization + solved problems from P&C Mission 1500 Series | Integron Maths.


Welcome to Lecture 28 of the Integron Maths Mission 1500 Series for JEE Mains & Advanced!
Today’s lecture covers the entire chapter of Circular Permutations using intuitive diagrams, chair models, beads, garlands, and real-life visual explanations from the class notes


In this power-packed session, you will learn:

🔵 What’s Covered in This Lecture

Circular Permutations basics

Rotational equivalence (4 rotations = same arrangement)

Linear vs Circular permutations

Identical chairs vs distinct chairs

Necklace arrangements (flipping allowed)

Garland / beads (clockwise vs anticlockwise same)

Round table arrangements

Circular permutations with restrictions

Mirrored arrangements (Page 10 diagram)

Advanced JEE Mains & JEE Advanced patterns

🧮 QUESTIONS DISCUSSED IN THE LECTURE (From PDF)
1️⃣ In how many ways can 6 friends be seated around a circular dining table?

2️⃣ In how many ways can a necklace be formed using 7 distinct colourful beads?

3️⃣ In how many ways can 6 Boys and 2 Girls sit at a round table if the 2 Girls must always sit together?

4️⃣ PM + 5 Ministers: PM has a fixed chair. Number of ways?

5️⃣ 21 pearls on a necklace; 3 specific pearls always remain together. How many ways?

6️⃣ 24 persons around a table if there are 13 sets?

7️⃣ 5 boys and 5 girls form a circle such that boys and girls alternate. How many ways?
