For e.g, the question states that L is proportional to d
Then it becomes, L1 = k1d1 & L2 = k2d2
Then calc the value of k.
Now, you will have to test validity.
Quote your ans like this : For relationship to be valid, |k1 - k2| / <k> should be less than 10 %
If greater than 10%, its not valid !
Okay ?

im afraid, its 20%.
there is another simple way and that is once you've calculated the two different values of k, find their percentage and if the result is greater than 80% say it is valid or your calculations support the suggested relationship. i.e k1=25 and k2=56 use, 25/56*100 which gives 45%. that means the calculations does not support the result (as 45% is less than 80%)
