From the table

N=66,

 N/2=66/2=33, which lies in the interval 10−15.

Hence, lower limit of the median class is 10.

The highest frequency is 20, which lies in between the interval 15−20.

Hence, lower limit of modal class is 15.

Therefore, required sum is 10+15=25.

Hence, option (B) is correct.
