- 7
- None of these
Correct Option: B
According to question,
If the positions of the first and the fifth digits of the number 83721569 are interchanged.
After interchange the new number = 13728569
similarly, the positions of the second and the sixth digits are interchanged.
Again after interchange the new number = 15728369
New arrangement of numbers is as follows: 15728369
Hence, third number from right end is 3.
