To find the average monthly production for the year, we first need to calculate the production for each month and then find the sum of all monthly productions. Finally, we divide the sum by 12 (the number of months in a year).

Let's calculate the production for each month:

January: 1000 tonnes (given)

For the subsequent months, we will apply the percentage increase to the previous month's production.

February: 1000 + (5/100 * 1000) = 1000 + 50 = 1050 tonnes
March: 1050 + (7/100 * 1050) = 1050 + 73.5 = 1123.5 tonnes
April: 1123.5 + (10/100 * 1123.5) = 1123.5 + 112.35 = 1235.85 tonnes
May: 1235.85 + (4/100 * 1235.85) = 1235.85 + 49.434 = 1285.284 tonnes
June: 1285.284 + (8/100 * 1285.284) = 1285.284 + 102.82272 = 1388.10672 tonnes
July: 1388.10672 + (5/100 * 1388.10672) = 1388.10672 + 69.405336 = 1457.512056 tonnes
August: 1457.512056 + (7/100 * 1457.512056) = 1457.512056 + 102.026044 = 1559.5381 tonnes
September: 1559.5381 + (6/100 * 1559.5381) = 1559.5381 + 93.572286 = 1653.110386 tonnes
October: 1653.110386 + (12/100 * 1653.110386) = 1653.110386 + 198.37324632 = 1851.483632 tonnes
November: 1851.483632 + (10/100 * 1851.483632) = 1851.483632 + 185.1483632 = 2036.631995 tonnes
December: 2036.631995 + (8/100 * 2036.631995) = 2036.631995 + 162.9305596 = 2199.562555 tonnes

Now, let's sum up all the monthly productions:

Sum = 1000 + 1050 + 1123.5 + 1235.85 + 1285.284 + 1388.10672 + 1457.512056 + 1559.5381 + 1653.110386 + 1851.483632 + 2036.631995 + 2199.562555

Sum = 17341.010444 tonnes

Finally, we find the average monthly production by dividing the sum by 12:

Average monthly production = Sum / 12
Average monthly production = 17341.010444 / 12
Average monthly production ≈ 1445.084204 tonnes

Therefore, the average monthly production for that year is approximately 1445.08 tonnes.
연도별 월별 평균 생산량을 구하려면 먼저 각 월의 생산량을 계산한 다음 모든 월별 생산량의 합을 구해야 합니다. 마지막으로 합계를 12(1년 동안의 월 수)로 나눕니다.

각 월의 생산량을 계산해 보겠습니다:

1월: 1000톤(주어진 값)

이후 달에는 전월 생산량에 백분율 증가율을 적용합니다.

2월: 1000 + (5/100 * 1000) = 1000 + 50 = 1050톤
3월: 1050 + (7/100 * 1050) = 1050 + 73.5 = 1123.5톤
4월: 1123.5 + (10/100 * 1123.5) = 1123.5 + 112.35 = 1235.85톤
5월: 1235.85 + (4/100 * 1235.85) = 1235.85 + 49.434 = 1285.284톤
6월: 1285.284 + (8/100 * 1285.284) = 1285.284 + 102.82272 = 1388.10672톤
7월: 1388.10672 + (5/100 * 1388.10672) = 1388.10672 + 69.405336 = 1457.512056톤
8월: 1457.512056 + (7/100 * 1457.512056) = 1457.512056 + 102.026044 = 1559.5381톤
9월: 1559.5381 + (6/100 * 1559.5381) = 1559.5381 + 93.572286 = 1653.110386톤
10월: 1653.110386 + (12/100 * 1653.110386) = 1653.110386 + 198.37324632 = 1851.483632톤
11월: 1851.483632 + (10/100 * 1851.483632) = 1851.483632 + 185.1483632 = 2036.631995톤
12월: 2036.631995 + (8/100 * 2036.631995) = 2036.631995 + 162.9305596 = 2199.562555톤

이제 모든 월별 생산량을 합산해 보겠습니다:

합계 = 1000 + 1050 + 1123.5 + 1235.85 + 1285.284 + 1388.10672 + 1457.512056 + 1559.5381 + 1653.110386 + 1851.483632 + 2036.631995 + 2199.562555

합계 = 17341.010444톤

마지막으로 합계를 12로 나누어 월별 평균 생산량을 구합니다:

월별 평균 생산량 = 합계 / 12
월별 평균 생산량 = 17341.010444 / 12
월별 평균 생산량 ≈ 1445.084204톤

따라서 해당 연도의 월별 평균 생산량은 약 1445.08톤입니다.
