Class interval	0 - 10	10 - 20	20 - 30	30 - 40	40 - 50
Frequency	7	13	14	5	11

पर्याय

• Between 20 and 22.5

• Between 27.5 and 30

• Equal to 25

• Between 22.5 and 27.5 but not equal to 25

Answer 1

Between 20 and 22.5

Explanation:-

Class interval	0 - 10	10 - 20	20 - 30	30 - 40	40 - 50
Frequency	7	13	14	5	11

Modal Class is 20 - 30

`"Mode" = l +((f_1-f_0)/(2f_1-f_0-f_2))xxh`

`=20+(14-13)/(28-13-5)xx10=21`

Hence, the mode will be between 20 and 22.5
