_______________
Second | 257
_______________
Third | x
_______________

Average Runs = 230 ( Given )

***********************************

Average= (Total Runs )/( No. of matches )

*************************************

( 180 + 257 + x )/3 = 230

=> 437 + x = 3 × 230

=> x = 690 - 437

x = 253

The number runs Scored by the

Answer 2

Answer:

runs in 1at match=180

runs in 2nd match =257

runs in 3rd match=x

average =230

Average=180+257+x/3

230=437+x/3

230*3=437+x

690=437+x

690-437=x

253=x

runs obtain in the 3rd match is 253.....
