The average of the runs of a cricket player in 20 matches is 35. If the average of the first 12 matches is 45, find the average of the last 8 matches.
Answer & explanation
Correct answer: option 4
Sum of runs scored in 20 matches = 20 × 35 = 700
Sum of runs scored in first 12 matches = 12 × 45 = 540
Runs scored in last 8 matches = 700 - 540 = 160
Average of runs scored in last 8 matches = \(\frac{160}{8}\) = 20
