1. 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,

   [tex] \: \: \sf \: average = \frac{total \: number \: of \: items}{sum \: number \: of \: items} [/tex]

   Now put on forumla

   [tex] \: \sf \: 40 = \frac{totalnumber}{1000} \\ \\ \: \: \sf \: total \: number = \frac{1000}{40} \\ \\ \: \: \sf \: total \: number = 25[/tex]

   Hence,total number of scores is 25.
