Solution

The correct option is A
34

$\begin{matrix} R a n g e & F r e q u e n c y & C u m u l a t i v e f r e q u e n c y 0 - 10 & 5 & (b) = 5 10 - 20 & (a) = 8 - 5 = 3 & 8 20 - 30 & 2 & (c) = 8 + 2 = 10 30 - 40 & 6 & (d) = 10 + 6 = 16 \end{matrix}$

So a + b + c + d = 3 + 5 + 10 + 16 = 34.

Range Frequency Cumulative frequency 0−105(b)10−20(a)820−302(c)30−406(d) Fill in the missing slots and find the value of (a)+(b)+(c)+(d).

The correct option is A 34 Range Frequency Cumulative frequency 0−105(b)=510−20(a)=8−5=3820−302(c)=8+2=1030−406(d)=10+6=16 So a + b + c + d = 3 + 5 + 10 + 16 = 34.

$\begin{matrix} R a n g e & F r e q u e n c y & C u m u l a t i v e f r e q u e n c y 0 - 10 & 5 & (b) 10 - 20 & (a) & 8 20 - 30 & 2 & (c) 30 - 40 & 6 & (d) \end{matrix}$

Fill in the missing slots and find the value of $(a) + (b) + (c) + (d)$ .

The correct option is A
34

$\begin{matrix} R a n g e & F r e q u e n c y & C u m u l a t i v e f r e q u e n c y 0 - 10 & 5 & (b) = 5 10 - 20 & (a) = 8 - 5 = 3 & 8 20 - 30 & 2 & (c) = 8 + 2 = 10 30 - 40 & 6 & (d) = 10 + 6 = 16 \end{matrix}$

So a + b + c + d = 3 + 5 + 10 + 16 = 34.
