The average runs scored by Sunil in 17 innings is 37. What is his score in the 17th inning, thereby, increasing his average score by 9 runs?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 181.
We know that,
Average = Sum of observations/Number of observations
Let the runs scored in the 17th inning be x
Average till 16th innings = 37 - 9 = 28
According to the question;
⇒ 28 × 16 + x = 37 × 17
⇒ x = 629 - 448 = 181
