Answer 1

Answer:

Median = size of (N+12)th item

Median = size of (N+12)th item    or, M = size of (15+12)th item

Median = size of (N+12)th item    or, M = size of (15+12)th item    or, M = size of 8th item

Median = size of (N+12)th item    or, M = size of (15+12)th item    or, M = size of 8th item    ⇒  M = 23

Median = size of (N+12)th item    or, M = size of (15+12)th item    or, M = size of 8th item    ⇒  M = 23Therefore, the median marks in the economics paper is 23.
