Tᴏ ꜰɪɴᴅ

Score in 5th innings

Sᴏʟᴜᴛɪᴏɴ

Here, scores in 4 innings = 14,30, 40 & 10

Let the score in 5th innings be = y

We know that,

⇾ Average Score = Total score/Number of innings

Pᴜᴛᴛɪɴɢ ᴠᴀʟᴜᴇꜱ ᴡᴇ ɢᴇᴛ :

⇾ 20 = (14 + 30 + 40 + 10 + y)/5

⇾ 20 × 5 = 94 + y

⇾ 100 = 94 + y

⇾ 100 - 94 = y

⇾ y = 6

Tʜᴇʀᴇꜰᴏʀᴇ,

His score in 5th innings = 6

Answer 2

Answer:

Average score in 5 innings=20

score in 4 innings=14,30,40 and 10.

let the score in 5th match=x

According to question:-

$\frac{14 + 30 + 40 + 10 + x}{5} = 20$

$\frac{94 + x}{5} = 20$

$94 + x = 20 \times 5$

$94 + x = 100$

$x = 100 - 94$

$x = 6$

The runs in 5th match are 6 runs.
