शब्द (COCO) के अलग-अलग arrangements कितने होंगे?

How many distinct arrangements are possible for the word (COCO)?

Explanation opens after your attempt
Correct Answer

C. (6)

Step 1

Concept

(C) occurs twice and (O) occurs twice, so \(\frac{4!}{2!2!}=6\). Divide by both repeated letters.

Step 2

Why this answer is correct

The correct answer is C. (6). (C) occurs twice and (O) occurs twice, so \(\frac{4!}{2!2!}=6\). Divide by both repeated letters.

Step 3

Exam Tip

(C) दो बार और (O) दो बार हैं इसलिए \(\frac{4!}{2!2!}=6\)। दो repeated letters हों तो दोनों से भाग दें।
