Expenditure on manufacturing = x/N100,000,000 × 3600 = 360
3600x = 360 × N100,000,000
x = 360×N100,000,000/3600
x=N10,000,000

For member of odd number items. That is, where N is odd
Median=([N/2]th + [N/2 + 1]th)/2
For member of odd number items. That is, where N is odd
Solution:
From the table, there are 20 members as indicated by the cumulative frequency. Since the members are odd (10) the median age will be ([N/2]th + [N/2 + 1]th)/2
Median=([10/2]th + [10/2 + 1]th)/2
=(5th + 6th)/2
The 5th member is 3 and the 6th member is on 3
Median=(3 + 3)/2
=6/2
Median = 3
