Correct Option: A
N = \(\sum f\) = 15
Hence the median age is the \(\frac{N + 1}{2}\)th age, i.e.
\(\frac{15 + 1}{2}\)th = 8th
From the table, the age that falls on the 8th position when arranged in ascending order is 25years
Hence the median age is the \(\frac{N + 1}{2}\)th age, i.e.
\(\frac{15 + 1}{2}\)th = 8th
From the table, the age that falls on the 8th position when arranged in ascending order is 25years
