Question

The number of permutations of letters in words BALBHARATI
a) 10! 3!
b)10!÷2!3!
c) 4! X 3!
d) 7! 3!​

Answer 1

Answer:

option B is correct

Step-by-step explanation:

BALBHARATI has 10 letters therefore this will 10!

B has repeated 2 times therefore 2!

A has repeated 3 times therefore 3!

10!/2!3!

Answer 2

Answer:

b) 10! /(2! 3!)

Step-by-step explanation:

There are letters repeating in the word given.

The letter Brepeats twice. The letter A repeats thrice. Any permutations among the 3 A's will be the same, ie, 3!. Similarly for the B's, 2! permutations. Hence to obtain the distinct permutations we divide the total permutations by these repeating permutations.

Total number of letters = 10.

So the number of different permutations of the word are

= 10! /(2! 3!)
