From the following data, cumulative frequency for the class $20-30 isClass | 0-10 | $10-20 | $20-30 | $30-40 | $40-50 ---|---|---|---|---|---Freq | 4 | 6 | $20 | 8 | 3

Option d: $30$. Solution: We are given the simple frequencies of classes: - Class 0-10 : Freq = 4 - Class $10-20 : Freq = 6$ - Class $20-30 : Freq = $20 - Class $30-40 : Freq = 8$ - Class $40-50 : Freq = 3$ The cumulative frequency for the class $20-30 is the sum of frequencies of all classes up to $20-30 : Cumulative frequency = Freq(0-10) + Freq(10-20) + Freq(20-30) Cumulative frequency = 4 + 6 + 20 = 30 This matches Option D. Hence, Option D is the correct answer.

The correct answer is Option d: $30$. We are given the simple frequencies of classes: - Class 0-10 : Freq = 4 - Class $10-20 : Freq = 6$ - Class $20-30 : Freq = $20 - Class $30-40 : Freq = 8$ - Class $40-50 : Freq = 3$ The cumulative frequency for the class $20-30 is the sum of frequencies of all classes up to $20-30 : Cumulative frequency = Freq(0-10) + Freq(10-20) + Freq(20-30) Cumulative frequency = 4 + 6 + 20 = 30 This matches Option D. Hence, Option D is the correct answer.

Correct Answer

✅ Option d — $30$

All Options:

A$26$
B$10$
C$41$
D$30$

Detailed Solution & Explanation

We are given the simple frequencies of classes: - Class

\displaystyle 0-10

: Freq =

\displaystyle 4

- Class $10-20

\displaystyle : Freq =

6$ - Class $20-30

\displaystyle : Freq = &#36;20

- Class $30-40

\displaystyle : Freq =

8$ - Class $40-50

\displaystyle : Freq =

3$ The cumulative frequency for the class $20-30

\displaystyle is the sum of frequencies of all classes up to &#36;20-30

Cumulative frequency = Freq (0 - 10) + Freq (10 - 20) + Freq (20 - 30)

Cumulative frequency = 4 + 6 + 20 = 30

This matches Option D. Hence, **Option D** is the correct answer.
