Felix, Gerald, Herman and Indrah shared the cost of a present. Felix paid 1/4 of the amount paid by Gerald, Herman and Indrah. The ratio of the amount paid by Gerald to the total amount paid by Herman and Indrah is 3 : 5. The

ratio of the amount paid by Herman to the amount paid by Indrah is 3: 7.
Given that Felix paid $12 less than Indrah, find the cost of the present.

Let the amount paid by Gerald be represented by $x. Then, Felix paid $\frac{1}{4}x$.

The total amount paid by Herman and Indrah is $3k + 7k = 10k$, where $k$ is a constant.
Since the ratio of the amount paid by Gerald to the total amount paid by Herman and Indrah is 3:5, we can write:
$$\frac{x}{10k} = \frac{3}{5}$$
Solving for $k$, we get $k = \frac{5x}{6}$
The amount paid by Herman is $\frac{3}{10}(10k) = \frac{3}{2}k = \frac{5x}{4}$.
The amount paid by Indrah is $\frac{7}{10}(10k) = \frac{7}{6}x$.
Since Felix paid $12 less than Indrah, we can write:
$$\frac{1}{4}x = \frac{7}{6}x - 12$$
Solving for $x$, we get $x = 72$.
Therefore, the total amount paid for the present is $10k = 5x = \boxed{360}$.

The bot is wrong. Can't find his error because of the weird format

it is using again.

My solution: (and it works)
Herman : Indrah = 3 : 7 = 3x : 7x
total of H and I = 10x

Gerard : (H and I) = 3 : 5 = 6 x : 10x
so we have:
G = 6x , H = 3x, I = 7x for a total of 16x
Felix paid 1/4 of 16x, so F = 4x

we are also told that 7x - 4x = 12
3x = 12
x = 4

final result:
Gerard paid $24
Herman paid $12
Indrah paid $28
Felix paid $16 , for a total for the gift of $80

Apologies for the confusion in the previous answer. Yes, the correct solution is as follows:

Let's assume the total cost of the present to be $x.

Given that Felix paid 1/4 of the amount paid by Gerald, Herman and Indrah, we can write:

Felix = (1/4)(G + H + I) ---------------- (1)

Also, the ratio of the amount paid by Gerald to the total amount paid by Herman and Indrah is 3:5. So, we can write:

G/H+I = 3/5
=> 5G = 3(H+I)
=> H+I = (5/3)G ------------------ (2)

Again, the ratio of the amount paid by Herman to the amount paid by Indrah is 3:7, which means:

H/I = 3/7
=>I = (7/3)H -------------------- (3)

Also, given that Felix paid $12 less than Indrah, we can write:

I - F = 12
=> I - (1/4)(G+H+I) = 12
Substituting the values of G, H, and I from (1), (2), and (3), we get:

(7/3)H - (1/4)(G+H+(7/3)H) = 12
Simplifying this equation, we get:

H = 12

So, I = (7/3)H = 28, G = (3/5)(H+I) = 24, and F = (1/4)(G+H+I) = 16.

Therefore, the total cost of the present is:

G+H+I+F = 24+12+28+16 = $80

why does the bot always have to make it so complicated???

That's a joke, just take another look at your weird and wrong first solution
then your convoluting method for your second post, lol
