The average runs of a cricket player in 20 matches is 30. If the average of the first 12 matches is 40, find the average of the last 8 matches.
Answer & explanation
Correct answer: option 2
Let average runs of last 8 matches = A runs
According to question ,
12 × 40 + 8 × A = 20 × 30
480 + 8A = 600
8A = 120
A = \(\frac{120}{8}\) = 15
So , average runs of last 8 matches = 15 runs
