Show Answer

 For Upper First Circle: Value in left segment = Sum of the Value in left segment in first and second lower circle. I.e Value of the any segment = Sum of the value in corresponding segments of lower circle. For Upper Middle Circle: Value of the any segment = Product of corresponding segments of lower circles. For upper Last Circle: Value in any segment = Difference of the corresponding segments of lower circles. Thus, Missing element, 7 + x = 10 x = 3.
