Other Exercises

Question 1.
Solution: Question 2.
Solution: Question 3.
Solution: Question 4.
Solution:
As the class 26 – 30 has maximum frequency so it is modal class Hence, mode = 28.5.

Question 5.
Solution:
As the class 1500 – 2000 has maximum frequency, so it os modal class Hence the average expenditure done by maximum number of workers = Rs. 1820.

Question 6.
Solution:
As the class 5000 – 10000 has maximum frequency, so it is modal class Hence, mode = Rs. 7727.27.

Question 7.
Solution:
As the class 15 – 20 has maximum frequency so it is modal class. Hence mode = 17.3 years.

Question 8.
Solution:
As the class 85 – 95 has the maximum frequency it is modal class Hence, mode = 85.71.

Question 9.
Solution:
The given series is converted from inclusive to exclusive form and on preparing the frequency table, we get

 Class Frequency 0.5 – 5.5 5.5- 10.5 10.5 – 15. 5 15.5 – 20.5 20.5 – 25. 5 25.5 – 30.5 30.5 – 35.5 35.5 – 40.5 40.5 – 45.5 45.5 – 50.5 3 8 13 18 28 20 13 8 6 3

As the class 20.5 – 25.5 has maximum frequency, so it is modal class Hence, mode = 23.28.
