(1) The product of the five integers in the list is 0.
(2) The sum of the given four integers divided by X is 0.



(1) NS

As the list is: {10, −2, −8, 0, X}, 1 term in the list is already 0. Hence what ever is the value of X, the product of the terms in the list is always 0.

(2) NS

As the list is: {10, −2, −8, 0, X}, And the sum of the given term is 0 (10+(-2)+(-8)+0) , already 0. Hence what ever is the value of X, the division 0/X will always fetch 0.

(1) & (2) ....... No conclusive info about X.

Answer E
