Question : 22

Anil played 8 cricket matches. The mean (average) of the runs was found to be 80. After playing four more matches, the mean of the runs of all the matches was found to be 70. The total runs made in the last four matches is
400
300
200
100
Validate
Solution:
Average of first 8 matches = 80
∴ Total runs of 8 matches = 8 × 80 = 640
after playing 4 more matches.
Total runs of 12 matches = 12 × 70 = 840
∴ total runs made in the last four matches = 840 - 640 = 200.
