Answer 1

Answer:

yes bro you are right answer is 31 & 30

Step-by-step explanation:

x+y+z+.......=310

average means dividing total sum by no. of terms

here no. of terms are 10

so

sum/10

=310/10

=31 is the average of 10 numbers

now

one no. is 40

40+y+z+........=310

y+z+.........=270

average=sum/no. of terms

average=270/9

=30 is average of 9 terms
