This is a confusing problem. As I read it, it kept going
in and out of focus. But I think I've got it now, and I also
think that NONE of the choices is correct.
We have to work with different values that 'a' and 'b' can be.
What are 'a' and 'b' ? The question says that they're integers
that we pick so that a·b is always 36. Can you think of another
way to say the same thing ?
'a' and 'b' are a factor pair of 36 ! That will help us write down
all the possible pairs of 'a' and 'b'. I'll do that in a second, but first ...
notice that the question is also going to talk about " a + b ",
so as I write down the factor pairs, I'll also write their sum next to
each one:
The factor pairs of 36 are:
1 and 36 . . . . . sum = 37
2 and 18 . . . . . sum = 20
3 and 12 . . . . . sum = 15
4 and 9 . . . . . . sum = 13
6 and 6 . . . . . . sum = 12 .
The question wants us to look through the list
for the biggest sum and the smallest sum, and
then figure out the difference between them.
That's easy !
The biggest sum is 37 .
The smallest sum is 12 .
The difference is (37 - 12) = 25 .
I don't see that among the choices.
But if I understand the question, then
that's my answer, and I'm sticking to it.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.
It is a method that we use for most of the calculations in math.
We can divide 20 by 10 to get the answer.
Therefore, by the unitary method answer will be 2.

The MAD of set 1 is 10.5 less than the MAD of set 2.
What is MAD?
MAD is mean absolute deviation which is calculated by
MAD = ∑₁ⁿ(|x - μ|)/n
Given data of set 1 : 5,10,7,2
and set 2: 5,10,7,42
MAD of set 1 = MAD(1) = ∑₁ⁿ(|x - μ|)/n
where μ is mean of set 1 and x are the entries of set and n is no. of entries,
μ =( 5+10+7+2)/4 =24/4 =6
now reduce the values of set 1 from mean
|x - μ| of set = 1,4,1,4
MAD(1) = ∑₁ⁿ(|x - μ|)/n = (1+4+1+4)/4 =10/4
MAD(1) = 2.5
MAD of set 2 = MAD(2) = ∑₁ⁿ(|x - μ|)/n
calculate mean for set 2
μ =( 5+10+7+42)/4 =64/4 = 16
now reduce the values of set 2 from mean
|x - μ| of set = 11,6,9,26
MAD(2) = ∑₁ⁿ(|x - μ|)/n =(11+6+9+26 )/4 =52/4
MAD(2) = 13
MAD(2) - MAD(1) = 13-2.5 = 10.5
Hence the set 1 is 10.5 less then set 2

Answer:
the answer is C
Step-by-step explanation:
if you do 5+10+7+2 you get 24 divide by 4 you get 6 mean is 6 for set 1
Set 2 if you do 5+10+7+42 you get 64 divide by 4 and you get 16 16-10.5 you get so 5.5 set is less than set 2 there ya go dude
