Answer 2

Step-by-step explanation:

ans. mean = sum of total observation / no. of observations

ATQ,

let the sum of total points scored in 8 matches be x

x/8 = 27

x = 216

given after three more matches his mean was 29.

new mean = x + (points in last three games)/8+3

29 = x + (points in last three games)/11 x + (points in last three games)= 319

we know that x = 216
