Explanation:

Correct option 3: 181

Given:
The average run scored by Sunil in 17 innings = 37.
total no. of observations
Let Sunil's score in the 17th inning be x.
His average until the 16th inning was = 37 - 9 = 28.
Therefore, his total score after the 16th inning = 16 x 28
⇒ 448
Then, after the 17th inning,
(16x28)+x/17 = the average of 17th inning
= (16 x 28) + x = 37 x 17
448 + x = 629
⇒x= 629-448
⇒x=181
:. Sunil scored 181 runs in the 17th inning.
