a) 120
b) 360
C)80
d) 96

Answer 1

$\fontsize{18}{10}{\textup{\textbf{Correct option is (d) 96.}}}$

Step-by-step explanation:

In the word PETROL, there are six letters.

Since the first letter oi foxed as P, so for the first letter, we have 1 option.

For the last letter, we have 4 options, because P is already fixed and L cannot be the last letter.

For the other four positions, we have 4, 3, 2 and 1 option left.

Therefore, the number of words that can be formed is

$1\times4\times4\times3\times2\times1=96.$

Thus, the required number of words is 96.

Option (d) is CORRECT.
