Question

A group of 10 men have A.M. 8 and a group of 15 women have A.M. 6 then the combined arithmetic mean of entire group is
A) 7
B) 6.8
C) 5
D) 5.8

Answer 1

Answer:

A) 7

Step-by-step explanation:

According to the information provided in the question it is given as

A group of 10 men have= A.M. 8

A group of 15 women have=A.M. 6

We need to find the combined arithmetic mean of entire group

First understand the meaning of arithmetic mean

The mean is the mathematical average of a set of two or more numbers that can be computed with the arithmetic mean method or the geometric mean method.

In the context of mathematics and statistics, the word mean refers to what's informally called the average—the sum of a set of values divided by the number

Here number = n=2

Data = 8 ,6

Mean = Addition of data / n

Substituting the value we get the answer

Mean = $\frac{8+6}{2}$

Hence option (A) 7 is correct answer

Answer 2

A) 7

this is the answer

this answer is easy
