Answer:
9 पारियों के बाद उसका रन औसत होगा 66 ।
Step-by-step explanation:
let the runs scored in 8 innings be a.
Therefore, average runs scored in 8 innings
= a/8. Let it be x. ..... (i)
The player scores 50 runs in the 9th inning
thus, average score in 9 innings = (a +50)/9
But, score decreases by 2 after 9th inning
i.e. (a+50)/9 = x-2
x = (a+50)/9+2
therefore, from (i)
a/8 = (a+50)/9+2
a/8 = a+50+18/9
after solving we get,
a = 544
using the value of a in a/8
we get, (544)/8 = 68
9 पारियों के बाद उसका रन औसत होगा x - 2 = 68-2 = 66 ।
