Question

The letters of the following words are arranged and words thus formed are kept separately as in a dictionary. Then, arrange the following in descending order of their individual ranks.
A : SITA B : RAMU C : TEA D : BUT

• A. DCBA
• B. ABDC
• C. ABCD
• D. BACD

Answer 1

The correct option is C ABCD

The rank of $SITA$ will be
$3!+3!+2!+1+1$
$=12+2+2$
$=16$
The rank of $RAMU$ will be
$3!+3!+1$
$=12+1$
$=13$
$TEA$ is the last word formed using the letter $A,E,T$, where none is repeated.
Hence, its rank will be $3!$
$=6$
$BUT$ is the second word in the total number of words formed using $B,T,U$ where none is repeated.
Hence, its rank is $2$.
Arranging in descending order, we get
ABCD.
