Answer 1

the value of the smallest number is 25

Answer 2

Sum and difference problem
--------------------------------------

We are given both the sum and difference of two unknown numbers.

S=sum of the two numbers=45,  and
D=difference of the two numbers (larger minus the smaller) = 37
Then
larger number = (S+D)/2 = (45+37)/2 = 41
smaller number= (S-D)/2 = (45-37)/2 =   4
