SOLUTION IS IN THE ATTACHMENT..
Median:
Median is that value of the given observation which divides it into exactly two parts.

MEDIAN for the GROUPED data :

For this we find the Cumulative frequency(cf) of all the classes and n/2 , where n = number of observations.

Now find the class whose Cumulative frequency is greater than and nearest to n/2 and this class is called median class,then use the following formula calculating the median.

MEDIAN = l + [(n/2 - cf )/f ] ×h

Where,
l = lower limit of the median class
n = number of observations
cf = cumulative frequency of class interval preceed the median class
f = frequency of median class
h = class size
