The plane denoted by `P_1 : 4x+7y+4z+81=0` is rotated through a right angle about its line of intersection with plane `P_2 : 5x+3y+10z=25`. If the plane in its new position be denoted by P, and the distance of this plane from the origin is d, then the value of `[(k)/(2)]` (where[.] represents greatest integer less than or equal to k) is....
