Answer 1

Ans 9. Mean = sum of all terms / no. of terms
here for 1st case (let x be sum of all terms)
27= X/8
so X= 216 (1)
now since a no. is included assume Y
26= (X+Y)/9
So , X+Y=234
Y=18
So, included no. is 18

Ans 10. In a week :
(Assume total birth rate to be X )
35=X/7
X=245
For Monday to Thursday :
32=Y/4
Y=128
For Thursday to Sunday :
36=Z/4
Z=144
Since Thursday is repeated so ( Y + Z ) - X is the birth rate on Thursday
Birth rate on Thursday is
(128+144)-245
=27
So, birth rate on Thursday is 27.
