Find his Average After 17th :
A batsman makes a score of 87 runs in the 17th inning and thus increased his average by 3. Find his average after 17th
- 90
- 84
- 39
- 87
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.
