Which of the following is a valid formula?

(C2-D16)

O A2/F2

O=B5/10

O = E10

=B5/10

=E10

Explanation:

The above two formulas are the correct options. Remember for a valid formula in Excel, we must have the = sign first, and this should be followed by a valid formula. Saying that C5 should be E10 by writing = E10 at C5 is a formula certainly. And storing B5/10 at C5, through = B5/10 is also a valid formula. Hence, two formula out of four, and as mentioned above are the correct ones.
