If the first and the third letters in the group DISTRIBUTION are interchanged and also the second and the fourth letter, the fifth and the seventh and so on, then which of the following would be the seventh letter from the left?
To find the seventh letter in the new arrangement, we first need to understand and apply the swapping rule to the original word "DISTRIBUTION".
The rule involves swapping pairs of letters:
This pattern continues for the entire word. Let's list all the pairs of positions that will be swapped:
(1st, 3rd), (2nd, 4th), (5th, 7th), (6th, 8th), (9th, 11th), (10th, 12th)
The original word is: D I S T R I B U T I O N
Let's find the new positions of the letters:
We only need to find the seventh letter, so we can stop here.
After the rearrangement, the seventh letter from the left is the letter that was originally in the fifth position, which is R.
