A person made 165 telephone calls in the month of May in a year . it was friday on 1st may of the year . the average of telephone calls on Sundays of the month was 7.What was the average of the telephone calls per day on the rest of the rest days of the month​

Answer 1

Explanation:

There are 31 days in May

Taking Friday on 1st May there will be 5 Sundays .

Let x be the total number of telephone calls made on all Sundays

Therefore ,

x/5=7

x=35

Hence , calls made on rest days are

=165-35

=130

Days other than Sunday in that month will be

=31-5

=26

Now average will be ,

=130/26

=5
