If the weight of A is 60 kg, weight of B is 45 kg and weight of C is 54 kg, What is the average weight of three persons?

A)
53 kg
B)
39 kg
C)
48 kg
D)
100 kg
E)
None of these

Answer: Option A

Explanation

Given weights are A= 60 kg, B= 45 kg, C= 54 kg,

We know the formula,

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

Here,

Sum of given weights (S)

= 60+45+54

= 159

Total number of persons (N)= 3

Substituting these values we get (A),

$= \frac{159}{3} = 53$

Hence, Option A is correct.

Find the average of the following set of scores 425, 361, 524, 621, 514, 555 ?

A)
500
B)
600
C)
700
D)
800
E)
None of these

Answer: Option A

Explanation

Given set of scores= 425, 361, 524, 621, 514, 555

We know the formula,

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

Here,

Sum of given values(S)

= 425+361+524+621+514+555

= 3000

Total number of values(N)= 6

Substituting these values we get (A),

$= \frac{3000}{6} = 500$

Hence, Option A is correct.

Find out the average of 101, 106, 116, 144 and 146?

A)
155
B)
135
C)

D)
122.6
E)
None of these

Answer: Option D

Explanation

Given set of scores= 101, 106, 116, 144, 146

We know the formula,

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

Here,

Sum of given values(S)

= 101+106+116+144+146

= 613

Total number of values(N)= 5

Substituting these values we get (A),

$= \frac{613}{5} = 122.6$

Hence, Option D is correct.

E)
None of these

Answer: Option A

Explanation

Given averages = 2, 5, 8, 11, 14, 17, 20, 23, 26, 29

We know the formula,

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

Here,

Sum of given values(S)

= 2+5+8+11+14+17+20+23+26+29

= 155

Total number of values(N)= 10

Substituting these values we get (A),

$= \frac{155}{10} = 15.5$

Hence, Option A is correct.

D)
2
E)
None of these

Answer: Option C

Explanation

Given averages =4, 4, 4, 4 , 4

We know the formula,

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

Here,

Sum of given values(S)

= 4+4+4+4+4

= 20

Total number of values(N)= 5

Substituting these values we get (A),

$= \frac{20}{5} = 4$

Hence, Option C is correct.
