शब्द (BANANA) के अलग-अलग अक्षर-क्रम कितने होंगे?

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

Explanation opens after your attempt
Correct Answer

B. (60)

Step 1

Concept

(A) occurs three times and (N) twice, so \(\frac{6!}{3!2!}=60\). Divide by factorials of repeated groups.

Step 2

Why this answer is correct

The correct answer is B. (60). (A) occurs three times and (N) twice, so \(\frac{6!}{3!2!}=60\). Divide by factorials of repeated groups.

Step 3

Exam Tip

(A) तीन बार और (N) दो बार है इसलिए \(\frac{6!}{3!2!}=60\)। repeated groups के factorial से भाग दें।
