A team of 8 persons joins in a shooting competition. The best marksman scored 85 points. If had scored 92 points, the average score for the team would have been 84. The number of points, the team scored was-

A. 588

B. 645

C. 665

D. 672

Answer: Option C

Solution(By Examveda Team)

Let the total score be x
$$\eqalign{ & \therefore \frac{{x + 92 - 85}}{8} = 84 \cr & \Rightarrow x + 7 = 672 \cr & \Rightarrow x = 665 \cr} $$
