The maximum value of F in the following equation 5E9 + 2F8 + 3G7 = 1114 is:

Answer: Option C

According to the question,
$$\begin{array}{rl}& 5E9\\ & 2F8\\ & 3G7\\ & \underline{\overline{1114}}\end{array}$$
⇒ Sum of 2, E, F and G must be 11. For maximum F we will have to take E and G zero.
∴ F = 9
