The best way to solve questions related to Permutations and Combinations is to use the concept of Visualization.

Since, the word VERBAL has six letters, draw 6 blanks on your rough sheet.

_ _ _ _ _ _

Since the question asked for how many ways it can be rearranged, you must use **Permutations**. So, since there are totally 6 letters, the first blank can take all of the 6 letters.

Therefore, the first blank can be filled in 6 ways.6 _ _ _ _ _

Now, once a letter is used up for a blank, **it cannot be repeated.** Therefore, the second blank can take only 5 letters. 6 x 5 _ _ _ _

Similarly, the subsequent blanks can be filled one after another.

6 x 5 x 4 x 3 x 2 x 1 = 720 ways.
Many students tend to immediately calculate the answer as 6 x 6 = 36 ways.

However, this will only give you the ways in which you can form any 6 letter word (with or without meaning) using the letters of Verbal.
