Answer 2

hello users ....
we have given that:
Average of four numbers p,q,r,s
is = 6
the numbers,
p= 3
q= 5
r= 7

we have to find:
s= ?

solution:-
we know that :
Average of any four numbers
= (sum of all the numbers) / (total no. of numbers )

here,
=> A =(p+q+r+s)/ 4

=> 6 = (3+ 5+7 +s) / 4

=> 24 = 15 + s
=> s = 24 - 15 = 9 answer

⭐ hope it helps :)
