In 12 days a professional gamer got 6561 points
We know that average is ratio of the sum of all observations and the number of total observations.
For given question,
A professional gamer averaged a score of 534 points, every day, for 5 days.
⇒ 534 = (total score of 5 days) / 5
⇒ total score of 5 days = 534 × 5
⇒ total score points of 5 days = 2670 points
Then, for the next 3 days he scored a total of 1827 points.
So, the total points of 8 days would be,
total score points of 5 days + total score points of 3 days
⇒ 2670 points + 1827 points = 4497 points.
In another 4 days he averaged a score of 516 points each day.
⇒ 516 = (total score of 4 days) / 4
⇒ total score of 4 days = 516 × 4
⇒ total score points of 4 days = 2064 points
So, the total number of points he did in 12 days:
total score points of 5 days + total score points of 3 days + total score points of 4 days
= 2670 points + 1827 points + 2064 points
= 6561 points
Therefore, in 12 days a professional gamer got 6561 points
