Possible cases:
1. N before 100 ----- median is \(\frac{(140+180)}{2}\) = 160 i.e., \(\frac{(3rd +4th)}{2}\) Similarly,
2. N before 140 ----- median is \(\frac{(140+180)}{2}\) = 160
3. N before 180 ----- median is \(\frac{(n+180)}{2}\) = \(\frac{(180+n)}{2}\)
4. N before 220 ----- median is \(\frac{(180+n)}{2}\) = \(\frac{(180+n)}{2}\)
5. N before 260 ----- median is \(\frac{(180+220)}{2}\) = 200
6. N after 260 ----- median is \(\frac{(180+220)}{2}\) = 200


Hence , ans C
