Question

. A cricketer has an average of 28 runs in 24 innings. How many runs must he score in the 25th inning to make his average 29?​

Answer 1

Answer:

53 runs

Step-by-step explanation:

so technically, average is the numbers added divided by how many numbers.

So we have an average of 28 with 24 numbers. (24 numbers added together and divided by 24 is 28).

If we want to find the original number before we divided by 24, we would do times 24.

So, 28 × 24 = 672

Next, we need an average of 29 with 25 numbers.

So if we multiply those, we get 725.

Lastly, right now, there is a total of 674 runs, and we need 725 runs.

So for that, we have to subtract it.

725 - 672 = 53

Hence, the cricketer needs 53 more runs in the last inning.

Answer 2

Given :- A cricketer has an average of 28 runs in 24 innings.

To Find :- How many runs must he score in the 25th inning to make his average 29 ?

Answer :-

Let he score x runs in 25th inning .

so,

→ Average of 24 innings = 28

→ Total runs in 24 innings = 24 * 28 = 672

then,,

→ Total runs in 25 innings = (672 + x)

A/q,

→ (672 + x)/25 = 29

→ 672 + x = 29 * 25

→ 672 + x = 725

→ x = 725 - 672

→ x = 53 Runs (Ans.)

Hence, he must score 53 runs in 25th inning to make his average 29 .
