Answer 2

Answer:

The correct answer is option (a) i.e.,10.

The lower class limit between 10-20 class interval is 10.

But by subtracting 0.5 from the lower limit and adding 0.5 to the upper limit, the class limits can be from 9.5 to 20.5. So if 9.5 is in the options then it will be the answer otherwise it is 10.
