The median class is  155 - 160.

Step-by-step explanation:

To find, the median class = ?

Class interval     Frequency(f)    Cumulative frequency(cf)

140-145               5                        5

145-150               15                     20

150-155               25                   45

155-160              30                   75

160-165              15                    90

165-170              10                    100

Total            Σf = n = 100

\dfrac{n}{2} =\dfrac{100}{2} =50

Median class = 155 - 160

Thus, the median class is  155 - 160.
