excluding two L's we can write the letters 'baoon' in 5factorial divide by two factorial as 'o' is two times.
next there exist 6 places between the letters of "baoon" in which two L's should be filled so we can write it in 6factorial divide by 4 factorial..
finally, multiply 5 factorial divide by 2 factorial and 6factorial divide by 4 factorial.
thn u will get the answer.
