Question

Aiden refills three token machines in an arcade. He puts twice the number in machine A as in machine B, and in machine C , he puts 3/4 of what he put in machine A. The total amount of tokens was 18324. How many tokens does each machine have.

Answer 1

It is a possibility of being 16 or 5/6

Answer 2

Answer:

Machine A has 8144 tokens, machine B has 4072 tokens and machine C has 6108 tokens.

Step-by-step explanation:

Let call: X the number of tokens that machine A has, Y the number of tokens that machine B has and Z the number of tokens that machine C has.

From the sentence: He puts twice the number in machine A as in machine B, we can formulate the equation 1 as:

X = 2*Y

Solving for Y we can write the equation 1 as:

Y = X/2

From the sentence: in machine C , he puts 3/4 of what he put in machine A, we can formulate the equation 2 as:

Z = (3/4)*X

And from the sentence the total amount of tokens was 18324. we can formulate the equation 3 as:

X + Y + Z = 18324

So, if we replace the Y by X/2 and Z by (3/4)X on equation 3 and solve for X, we get:

X + Y + Z = 18324

X + X/2 + (3/4)X = 18324

(9/4)X=18324

X = 18324*(4/9)

X = 8144

Then, replacing this value on equation 1 and 2 to find Y and Z respectively, we get:

Y = X/2 = 8144/2 = 4071

Z = (3/4)*X = (3/4)*4071 = 6108

So, machine A has 8144 tokens, machine B has 4072 tokens and machine C has 6108 tokens.
