The frequency of the Class 20-30 isMarks | 0-10 | 10-20 | 20-30 | 30-40 | 40-50 ---|---|---|---|---|---Freq | 5 | 13 | 28 | 34 | 38

Option b: 28. Solution: From the given frequency distribution table, we read the frequency directly corresponding to the class interval 20-30 : - Class 0-10 : frequency = 5 - Class 10-20 : frequency = 13 - Class 20-30 : frequency = 28 - Class 30-40 : frequency = 34 - Class 40-50 : frequency = 38 The frequency of the class 20-30 is 28 , which corresponds to Option B. Hence, Option B is the correct answer.

The frequency of the Class $20-30$ isMarks | $0-10$ | $10-20$ | $20-30$ | $30-40$ | $40-50$---|---|---|---|---|---Freq | $5$ | $13$ | $28$ | $34$ | $38$

The correct answer is Option b: $28$. From the given frequency distribution table, we read the frequency directly corresponding to the class interval $20-30$: - Class $0-10$: frequency = $5$ - Class $10-20$: frequency = $13$ - Class $20-30$: frequency = $28$ - Class $30-40$: frequency = $34$ - Class $40-50$: frequency = $38$ The frequency of the class $20-30$ is $28$, which corresponds to Option B. Hence, **Option B** is the correct answer.

Detailed Solution & Explanation

From the given frequency distribution table, we read the frequency directly corresponding to the class interval

\displaystyle 20-30

: - Class

\displaystyle 0-10

: frequency =

\displaystyle 5

- Class

\displaystyle 10-20

: frequency =

\displaystyle 13

- Class

\displaystyle 20-30

: frequency =

\displaystyle 28

- Class

\displaystyle 30-40

: frequency =

\displaystyle 34

- Class

\displaystyle 40-50

: frequency =

\displaystyle 38

The frequency of the class

\displaystyle 20-30

\displaystyle 28

, which corresponds to Option B. Hence, **Option B** is the correct answer.
