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.

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

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 $20-30$: $$\text{Cumulative frequency} = \text{Freq}(0-10) + \text{Freq}(10-20) + \text{Freq}(20-30)$$ $$\text{Cumulative frequency} = 4 + 6 + 20 = 30$$ This matches Option D. Hence, **Option D** is the correct answer.

Correct Answer

✅ Option d — $\displaystyle 30$

All Options:

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

Detailed Solution & Explanation

We are given the simple frequencies of classes: - Class

\displaystyle 0-10

: Freq =

\displaystyle 4

- Class

\displaystyle 10-20

: Freq =

\displaystyle 6

- Class

\displaystyle 20-30

: Freq =

\displaystyle 20

- Class

\displaystyle 30-40

: Freq =

\displaystyle 8

- Class

\displaystyle 40-50

: Freq =

\displaystyle 3

The cumulative frequency for the class

\displaystyle 20-30

is the sum of frequencies of all classes up to

\displaystyle 20-30

\text{Cumulative frequency} = \text{Freq}(0-10) + \text{Freq}(10-20) + \text{Freq}(20-30)

\text{Cumulative frequency} = 4 + 6 + 20 = 30

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