उत्तर
In a frequency distribution with classes 0 – 10, 10 – 20 etc., the size of the class intervals is 10. The lower limit of fourth class is 30.
Explanation:
Given classes are 0 – 10 and 10 – 20.
As, the class of given classes is 10, so the next classes will be 20 – 30 and 30 – 40.
As, the fourth class is 30 – 40.
Hence, the lower limit of fourth class is 30.
