You can put this solution on YOUR website!
total score was 6996 in 69 test
new test play will have total test =69+1=70
to have average score greater than or equal to 100
total score should be 100x70 = 7000 score
run required in final match will be 7000-6996 =4
therefore to get average of 100 runs
he should make the run at least 4 or more
ANSWER 4 run or more
