उत्तर
True class limits: if classes are inclusive eg 15-19, 20-24, 25-29, 30-34...........
Then, true lower limit of class = upper limit of class -0.5
And true upper limit of class = upper limit of class +0.5
Example: true limits of the class 15-19 are 14.5 and 19.5
But if because classes are exclusive use like 10-20, 20-30, 30-40..........
Here class limits and true class limits are the same.
