GIVEN:
Bowler’s old average = 16.2
Bowler’s new Average = 15.4
FORMULA USED:
Bowling average = Total runs conceded/Total wicket taken
CALCULATION:
Let the total number of wickets be x
Then, bowling average = 16.2
Runs conceded = 16.2 x
Now, (16.2 x + 40)/(x + 4) = 15.4
16.2 x + 40 = 15.4 (x + 4)
16.2 x + 40 = 15.4 x + 61.6
0.8 x = 61.6 – 40
x = 21.6/0.8 = 27
Alternate method:
By Allegation:
Hence total number of wickets taken before last match = 27
(Note – if question is to find the number of wickets till last match, then answer will be = 27 + 4 = 31)

Given:
- Bowler's previous average = 16.2 runs per wicket
- Bowler gave 40 runs and took 4 wickets in the last match
- Bowler's new average = 15.4 runs per wicket
To find:
- Number of wickets taken by the bowler before the last match
Solution:
Let's assume that the bowler had taken 'x' wickets before the last match.
Before the last match, the total runs given by the bowler = 16.2x
After the last match, the total runs given by the bowler = 16.2x + 40
Before the last match, the average runs given per wicket = 16.2
After the last match, the average runs given per wicket = 15.4
Using the formula for average, we can write:
Before the last match:
16.2x / x = 16.2
x = 16.2
After the last match:
(16.2x + 40) / (x + 4) = 15.4
16.2x + 40 = 15.4x + 61.6
0.8x = 21.6
x = 27
Therefore, the bowler had taken 27 wickets before the last match.
Answer: Option (c) 27
