Solution

The correct option is C Not proportional to b
Two variables are said to be in inverse proportion if the product of the two variables is constant.

Given, a(b+a)=10

ab+a2=10

ab=10a2, which is not a constant.

So, 'a' and 'b' are not inversely proportional to each other.

Two variables are said to be in direct proportion if their ratio is constant.

Now, ab=10b(b+a), which is also not a constant.

'a' and 'b' are not in direct proportion.

From the above two conditions we can say that 'a' is not in proportion with 'b'.
