Answer 1

Answer:

55

Step-by-step explanation:

how many runs to be scored by the player in the fifth innings to raise the mean score by five? 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

Answer 2

Answer:

75

Step-by-step explanation:

Given:

• The cricket player has a mean score of 50 runs in four innings

To find :

• What should be the score of the player in fifth innings to  raise the mean score by 5

Mean = sum of observations/No. of observations

50=sum/4

sum = 200 runs

As the condition is that mean should increase by 5 (50+5=55) in the fifth match

55 = Score/5

score = 275 runs

Score = 275-200 = 75 runs

75 runs shall be scored in 5th innings to increase the mean score by 5
