Answer 2

Answer:

• Total number of scores is 25.

Given:

• Sum of all scores in the given data is 1000
• Average number of scores is 40.

To Find:

• Total number of scores is = ?

Solution:

According to the question,average number is given and sum of all numbers is given and we are said to find total numbers of scores.

As we know that,

$\: \: \sf \: average = \frac{total \: number \: of \: items}{sum \: number \: of \: items}$

Now put on forumla

$\: \sf \: 40 = \frac{totalnumber}{1000} \\ \\ \: \: \sf \: total \: number = \frac{1000}{40} \\ \\ \: \: \sf \: total \: number = 25$

Hence,total number of scores is 25.
