a cricket player has a mean score of 50 runs in the four innings. how many runs to be scored by the player in the fifth innings to raise the mean score by five?
Dear Student
Mean score of 4 innings = 50 runs.
Total score of 4 innings = (50 x 4) runs = 200 runs.
Required mean score of 5 innings = 50+5 =55 runs.
Required total score of 5 innings = (55 x 5) runs = 275 runs.
Number of runs to be scored in the 5th innings
= (total score of 5 innings) - (total score of 4 innings)
= (275 -200) = 75.
Hence, the number of runs to be scored in the 5th innings = 75.
