In a Mathematics examination the number scored by 5 candidates are 5 successive odd integers. If their total marks are 185, the highest score is :

Answer: Option C

Let the five successive odd number be,
x, x + 2, x + 4, x + 6, x + 8
Then, according to given information,
185 = x + x + 2 + x + 4 + x + 6 + x + 8
$$\begin{array}{rl}& \iff 185=5x+20\\ & \iff 5x=185-20\\ & \iff 5x=165\\ & \iff x=33\end{array}$$
Highest number = 33 + 8 = 41
