Question

Number of arrangements of letters in MAHARASHTRA such that letters R and H are never together

Answer 1

Step-by-step explanation:

we can get the answer by subtracting the value r and h coming together from the total value

total value= 11!/2!*4!*2!= 11!/4*24= 415800

now r and h coming together

take R and h as a unit

8!*4!/2!*4!*2!= 10080

so the number of ways in which r and h will not come together is

415800-10080=405720
