Answer:
ans 76
Step-by-step explanation:
Average = total runs / no.of innings = 32
So, total = Average x no.of innings = 32 x 10 = 320.
Now increase in avg = 4runs. So, new avg = 32+4 = 36runs
Total runs = new avg x new no. of innings = 36 x 11 = 396
Runs made in the 11th inning = 396 - 320 = 76

Gɪᴠᴇɴ
Average run in 10 innings = 32
Next innings, his average would increase by 4.
Tᴏ ꜰɪɴᴅ
How much he should score in 11th innings to increase average by 4.
Sᴏʟᴜᴛɪᴏɴ
Case ❶
As we know that,
⇒ Average = Total runs/Number of innings
⇒ 32 = Total runs/10
⇒ Total runs = 32 × 10
⇒ Total runs = 320
Case ❷
Let the score in 11th innings be n.
⇒ (32 + 4) = (320 + n)/11
⇒ 36 = (320 + n)/11
⇒ 36 × 11 = 320 + n
⇒ 396 = 320 + n
⇒ n = 396 - 320
⇒ n = 76
Tʜᴇʀᴇꜰᴏʀᴇ,
He should score 76 runs in the next innings to increase his average by 4
