nice to know you have solved the problem. but it will be too good to clear things right here.
Hi Mr. Raghu,
interpolation is a numerical techneque based on calulus, that can be applied to sampled statstical data to guess the value of the random variable at the point where data wasn't been sampled. in order to do this we try to find a polynomial which fits into sampled data. the obtained polynomial the guessed relation between the data in two column.


Mr. paul posts a polinomial of degree two.


Deg = (1.31E-4 * MM^2) + (0.122 * MM) - 2.85

may be inter polation has been done by the fastest parallel computer in this world called brain :).
