Question

The positions of the first and second digits in the number 9 4 3 1 6 8 7 5 are interchanged. Similarly, the positions of the third and fourth digits are interchanged and so on. Which of the following will be the third to the left of the seventh digit from the left end after the rearrangement?
1. 6
2. 1
3. 4
4. None of these

Answer 1

Correct Answer - Option 4 : None of these

Given sequence: 9 4 3 1 6 8 7 5

Sequence after digits change thier position: 4 9 1 3 8 6 5 7 

Seventh digit from the left end: 4 9 1 3 8 6 5 7 

Third to the left of the seventh digit from the left end: 4 9 1 3 8 6 5 7 

Thus we can see 3 is third to the left of 5.

Hence, 'None of these' is the correct answer.
