A)
10
B)
8
C)
16
D)
9
E)
None of these

Answer: Option B

Explanation

Given averages =5, 7, 13, 0, 15

We know the formula,

$Average (A) = \frac{Sum of given values (S)}{Total number of values (N)}$

Here,

Sum of given values(S)

= 5+7+13+0+15

= 40

Total number of values(N)= 5

Substituting these values we get (A),

$= \frac{40}{5} = 8$

Hence, Option B is correct.

Here,

Sum of given values(S)

= 129+139+155+176

= 599

Total number of values(N)= 4

Substituting these values we get (A),

$= \frac{599}{4} = 149.75$

Hence, Option D is correct.

Here,

Sum of given values(S)

= 48+47+64+91+72+68+93

= 483

Total number of values(N)= 7

Substituting these values we get (A),

$= \frac{483}{7} = 69$

Hence, Option C is correct.

Here,

Sum of given values(S)

= 62+76+42+84+21+47+28

= 360

Total number of values(N)= 7

Substituting these values we get (A),

$= \frac{360}{7} = 51.42$

Hence, Option B is correct.
