All the words that can be formed using alphabets A, H, L, U, R are written as in dictionary (no alphabet is repeated). Then the rank of the word RAHUL is.......

Step-by-step solution

Given alphabets are A, H, L, U, R, so the number of words starts with letter ( A =4 !=24 ) The number of words starts with letter ( H =4 !=2.4 ) The number of words starts with letter ( L = 4 != 2 4 ) Now, the next word start with ( R ) and order wise words are RAHLU and RAHUL. So in dictionary order the rank of word RAHUL is (24+24+24+1+1=74 ) Hence, option (d) is correct.
