Answer 1

Answer:

37

Step-by-step explanation:

Let the Total scores of Sachin before 17 th innings be x

Mean be y

So now

(x+85)/17=m+3---->(1)

(x/16)=m-----(2)

Let's add equation 1 and 2

x+34=17m(by simplifying eq.1

x=16m

34=m

So the Mean after his 17 th inning is (34+3) 37.

Answer 2

Answer:

37

Step-by-step explanation:

let x be the average in 16 innings ,sum of observations number of observations×their average

So,The total score in 16 innings = 16x

Now the total score in 17 innings = 85,

total score in 17 innings = Total score in 16 innings+score in 17th innings

16x+85 again if the average 17 innings is x+3

the total score = 17(x+3)

If 16x+85 = 17(x+3)

16x+85 = 17x+51

85-51 = 16x-17x

34 = x

hence the average score in the 17th inning =34 +3 = 37
