. Four friends contribute the sum of money to a charitable organization in the

ratio 1:3:5:7. If the largest amount contributed is Birr 35. Calculate the total
amount contributed by the four people.

5 * ( 1 + 3 + 5 +7 )

3:5:7

three friends shared an amount in the ratio 3/3 : 3/5 : 1/4 . if the larg

To solve this problem, we need to find the sum of the contributions made by the four friends.

Let's call the amount contributed by the first friend "x". Since the ratio of their contributions is 1:3:5:7, the amounts contributed by the other friends can be expressed as 3x, 5x, and 7x, respectively.

We are given that the largest amount contributed is 35 Birr, which corresponds to the contribution made by the fourth friend (7x = 35). To find the value of x, we can divide 35 by 7:

7x = 35
x = 35/7
x = 5

Now that we know the value of x, we can calculate the contributions of the other friends:

Friend 1: x = 5 Birr
Friend 2: 3x = 3 * 5 = 15 Birr
Friend 3: 5x = 5 * 5 = 25 Birr
Friend 4: 7x = 7 * 5 = 35 Birr

To find the total amount contributed by the four friends, we add up their contributions:

Total = Friend 1 + Friend 2 + Friend 3 + Friend 4
Total = 5 + 15 + 25 + 35
Total = 80 Birr

Therefore, the total amount contributed by the four friends is 80 Birr.
