Step-by-step explanation:
Average run for 31 innings = 28.3
Total run for 31 innings = 28.3×27 ( 4times not out)
= 764.1
New average = 30
New total will be =30×29
= 870
So the required next inning runs =870- 764.1
= 105.9
= 106
Solution :-
given that,
→ Initial total innings he played = 31
→ Average score = 28.3 runs
So,
→ Total runs player scored = Average * Total innings = 28.3 * 31 = 877.3 runs .
now, let us assume that, in next inning he scored x runs so that his new average becomes 30.6 .
then,
→ Total runs he scored now = (877.3 + x)
→ Total innings now = 31 + 1 = 32
→ Average = 30.6
therefore,
→ Average = Total runs / Total innings
→ 30.6 = (877.3 + x)/32
→ 30.6 * 32 = 877.3
→ 979.2 = (877.3 + x)
→ x = 979.2 - 877.3
→ x = 101.9 runs
→ x ≈ 102 runs (Ans.)
