Question

in how many ways the word 'ARRANGE' be arranged such that 2 R's come together​

Answer 1

Step-by-step explanation:

let us bind two Rs so that it is treated as one letter

now, number of letters in the word is 6 (counting two Rs as one letter)

out of six letters, the letter A occurs twice.

hence number of arrangement is

6!/2!

= 3*4*5*6

= 360
