Question

6. Чотири бригади зібрали 1680 кг цибулі. Перша бригада зібрала 3/4 усієї цибулі, друга – 34% решти, третя – в 1целая 1/3 раза більше, ніж друга. Скільки цибулі зібрала четверта бригада? Очонь нужно! Зарание спасиба

Answer 1

1680*3/4=1260 кг зібрала перша
1680-1260=420 кг залишок
420*0,34=142,8 кг зібрала друга
142,8*1 1/3=142,8*4/3=190,4 кг зібрала третя
420-142,8-190,4=86,8 кг зібрала четверта

Answer 2

Problem Analysis

We are given that four brigades collected a total of 1680 kg of onions. The first brigade collected 3/4 of all the onions, the second brigade collected 34% of the remaining onions, the third brigade collected 1 1/3 times more than the second brigade, and we need to find out how many onions the fourth brigade collected.

Solution

Let's break down the problem step by step:

1. The first brigade collected 3/4 of all the onions. 2. The second brigade collected 34% of the remaining onions after the first brigade collected their share. 3. The third brigade collected 1 1/3 times more onions than the second brigade. 4. We need to find out how many onions the fourth brigade collected.

Let's calculate the amount of onions collected by each brigade.

Calculation

1. The first brigade collected 3/4 of all the onions: - Let's assume the total amount of onions collected by all four brigades is represented by x. - The first brigade collected 3/4 of x, which is (3/4)x.

2. The second brigade collected 34% of the remaining onions after the first brigade collected their share: - After the first brigade collected (3/4)x onions, the remaining onions are (1 - 3/4)x = (1/4)x. - The second brigade collected 34% of (1/4)x onions, which is (34/100) * (1/4)x = (17/100)x.

3. The third brigade collected 1 1/3 times more onions than the second brigade: - The third brigade collected (1 + 1/3) times the onions collected by the second brigade. - The onions collected by the second brigade are (17/100)x. - The onions collected by the third brigade are (4/3) * (17/100)x = (68/300)x.
