The average runs of a player in 6 matches is 37. How many runs he must score in the next match to make his average 40?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 58.
We know that,
Average = Sum of observations/Number of observations
The sum of run of 6 matches = 6 × 37 = 222
Let the run scored in 7th match be R
Total runs till 7th match = 222 + R
⇒ (222 + R)/7 = 40
⇒ (222 + R) = 280
⇒ R = 280 - 222
⇒ R = 58
Therefore, the player must score 58 runs in the next match to make his average of 40
