A. 8

B. 6

C. 12

D. 5

E. 10

Answer: Option A

Solution(By Examveda Team)

Let the missing number be x
$$\eqalign{ & \frac{{294 \div 14 \times 5 + 11}}{x} = {8^2} \div 5 + 1.7 \cr & \Rightarrow \frac{{\frac{{294}}{{14}} \times 5 + 11}}{x} = \frac{{64}}{5} + 1.7 \cr & \Rightarrow \frac{{21 \times 5 + 11}}{x} = 12.8 + 1.7 \cr & \Rightarrow \frac{{105 + 11}}{x} = 12.8 + 1.7 \cr & \Rightarrow \frac{{116}}{x} = 14.5 \cr & \Rightarrow x = \frac{{116}}{{14.5}} \cr & \Rightarrow x = \frac{{116 \times 10}}{{145}} \cr & \Rightarrow x = 8 \cr} $$
Hence, the number is 8
