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.

Correct Answer

✅ Option b — $28$

All Options:

A $\displaystyle 5$
B$28$
C$15$
D$13$

Detailed Solution & Explanation

From the given frequency distribution table, we read the frequency directly corresponding to the class interval $20-30$: - Class

\displaystyle 0-10

: frequency =

\displaystyle 5

- Class $10-20

\displaystyle : frequency = &#36;13

- Class $20-30

\displaystyle : frequency = &#36;28

- Class $30-40

\displaystyle : frequency = &#36;34

- Class $40-50

\displaystyle : frequency = &#36;38

The frequency of the class $20-30

\displaystyle is &#36;28

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