It is said that Earth attracts every body towards it's center. Now my question is, if the value of g in the centre of Earth is 0, then how it attracts any object towards it's centre.

Hey mate ,
Acceleration due to the earth's gravity is zero at the centre of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. As the distance from the centre decreases, the acceleration due to gravity also decreases.
