Answer: (3) 39

Explanation:-
Let the average after 17th innings = X
Then, the average after 16th innings = (X – 3)

According to the question,
16 (X – 3) + 87 = 17 X
16 X – 48 + 87 = 17 X
16 X + 39 = 17 X
17 X – 16 X = 39
X = 39

Then, the average after 17th innings is 39.

Hence, the answer is (3) 39.
