- 1
- 0
- None of these
Correct Option: B
According to given question,
If the positions of the first and the sixth digits of the group of digits 5904627813 are interchanged.
New number after interchange = 2904657813
Then the positions of the second and the seventh are interchanged.
New number after interchange = 2704659813
fourth from the right end after the rearrangement is 9.
In the original group of digits ‘7’ is fourth from the right, which is interchanged with ‘9’.
