Number of fitness trackers = x
Fitness trackers take 4 hours of assembly and 6 hours of software calibration
Profit = 40

Number of smart rings = y
Smart rings take 4 hours of assembly and 2 hours of software calibration
Profit = 30

Maximize profit = 40x + 50y

Statement 1
The cost of the components for each fitness tracker is twice that for each smart ring

There is no information about the time taken

Statement 1 is not sufficient

Statement 2
4x + 4y <= 200
6x + 2y <= 200

Solving,
x + y <= 50
3x + y <= 100

x <= 25
y <=25

Statement 2 is sufficient

IMO B

To determine how many fitness trackers the company should produce each week to maximize profit, we need to know the constraints on the production process and the profit contributions of each product. Let's analyze the information provided in the statements:
Given Information:
  • Fitness Tracker:
    • Assembly time: 4 hours
    • Software calibration time: 6 hours
    • Profit: $40 per unit
  • Smart Ring:
    • Assembly time: 4 hours
    • Software calibration time: 2 hours
    • Profit: $30 per unit
Statements:
(1) The cost of the components for each fitness tracker is twice that for each smart ring.
  • This statement provides information about the cost of components but does not give us any information about the constraints on assembly or software calibration time. Therefore, it does not help us determine the maximum number of fitness trackers to produce.
(2) The facility has the capacity for 200 hours of assembly time each week and 200 hours of software calibration each week.
  • This statement provides the necessary constraints on the production process. We can use this information to set up a system of linear equations to maximize profit.
Analysis of Statement (2):
Let x be the number of fitness trackers produced each week, and yy be the number of smart rings produced each week.
The constraints are:
  1. Assembly time: 4x+4y≤200
  2. Software calibration time: 6x+2y≤200
The objective is to maximize the profit:
Profit=40x+30y
Solving the Constraints:
  1. Simplify the assembly time constraint:
    4x+4y≤200
    x+y≤50
  2. Simplify the software calibration time constraint:
    6x+2y≤200
    3x+y≤100

Conclusion:
We can deternine using the 2 statements hence sufficient

Statement 1. Insufficient. No information about the the capacity. Beside we do not need the cost price since we already have the profit
Statement 2. Sufficient. With this information we can test extremes by assuming zero production of each and max assembly of each and by doing so we realize the company will maximize its profits by producing zero fitness trackers and instead produce 50 smart rings

We don't know the actual cost of the components of any of the devices, let's the cost is in decimals or it is in 100's of dollars, so we can't conclude any more profitable strategy.

We need to maximize profit by deciding how many fitness trackers (F) and smart rings (S) to produce.

Given :
  1. Profit = 40F + 30S
  2. Resource constraints:
    • Assembly: 4F + 4S ≤ Total Assembly Hours
    • Calibration: 6F + 2S ≤ Total Calibration Hours

(A) Talks about cost, not time constraints, so it doesn't help with maximizing profit. Insufficient.

(B) Assembly: 4F + 4S ≤ 200 → Simplifies to F + S ≤ 50
Calibration: 6F + 2S ≤ 200 → Simplifies to 3F + S ≤ 100

Now we have two linear equations. And we can solve (with linear programming) for unique values of F and S to maximize the profit. Sufficient.

Answer: B

t=number of fitness trackers
r=number of smart rings

time for t: 4a+6c
time for r: 4a+2c

profit for t: 40
profit for r: 30

maximize total profit=40t+30r

(1)
This information tells us about the cost structure of the components but does not directly affect the problem, which focuses on maximizing profit given the production time constraints.

INSUFFICIENT

(2)
assembly=200h
calibration=200h

4t+4r<=200 -> t+r<=50
6t+2r<=200 -> 3t+r<=100

To maximize profit=40t+30r, it is necessary to maximize t and r. It happens when all the possible hours (in assembly and calibration) are used:
t+r=50
3t+r=100 -> 3(50-r)+r=100 -> 150-2r=100 -> 2r=50 -> r=25 -> t=25

SUFFICIENT

We need to determine how many fitness trackers the company should produce each week to maximize profits. Let the number of fitness trackers produced each week be , and the number of smart rings produced each week be.

Information from the problem:

Each fitness tracker requires:

4 hours of assembly

6 hours of software calibration

Profit = $40 per unit


Each smart ring requires:

4 hours of assembly

2 hours of software calibration

Profit = $30 per unit



The company's objective is to maximize profit:

Profit = 40x + 30y.

Step 1: Analyze Statement (1)

Statement (1): The cost of the components for each fitness tracker is twice that for each smart ring.

This provides information about production costs but does not affect the constraints (assembly and calibration capacities) or the profit-maximization equation directly. Without knowing the facility's production capacity, we cannot determine how many fitness trackers should be produced.
Statement (1) alone is insufficient. Hence we can eliminate option (A) & by default option (D)

Step 2: Analyze Statement (2)

Statement (2): The facility has the capacity for 200 hours of assembly time each week and 200 hours of software calibration each week.

This provides the constraints:

4x+4y<=200 (assembly constraint),

6x+2y<=200 (software calibration constraint).


We now have a constrained optimization problem with two inequalities and an objective function:

Profit = 40x + 30y.

We solve this using linear programming methods. This is sufficient to determine the optimal number of fitness trackers (x) and smart rings (y).

Step 3: Combine Statements (1) and (2)

Combining the statements does not add any useful information. The cost of components (from Statement (1)) does not change the optimization process because profits are already given directly in the problem.

Final Answer:

Statement (2) alone is sufficient, but Statement (1) alone is not sufficient.

Hence the correct answer to this question is option (B)

Answer: B

To maximize the profit, the whole of the assembly & calibration hours should be utilized.

Statement 1: Since the profit was already given, cost of components are not sufficient

Not Sufficient

Statement 2: Total assembly hours are \(200\) & total calibration hours are \(200\)

\(4f+fs=200\)

\(6f+2s=200\)

Sufficient

To maximize the profit p = 40x + 30y
where x is no. of fitness trackers and y is no. of smart rings
statement 2) x+y <= 50 and 3x+y <= 100
y <= 50-x
by substituting 3x+(50-x)<=100 by equating, x <= 25
Therefore, the company produce 25 fitness trackers per week to maximize the profit
Option B) is correct , Statement 2 alone is sufficient

Answer is B. Statement 2 alone is sufficient

1) Doesn't give us any new information from the passage since we are already given the different profit amounts of the two items. We don't have any information about the actual weekly capacities. Insufficient.
2) We are given weekly capacities, so we can now calculate the optimal number of fitness trackers and smart rings to produce. Sufficient.

how many fitness trackers should the company produce each week to maximize profit for these two products?

Let number of fitness trackers be x, number of smart rings be y. We need to look for max (40x + 30y)

(1) The cost of the components for each fitness tracker is twice that for each smart ring.
Since we are maximizing the profit, the cost doesn't seem to be relevant.

(2) The facility has the capacity for 200 hours of assembly time each week and 200 hours of software calibration each week.

Assembly time of both fitness trackers and smart rings:
4x + 4x <= 200
So 5x + 5y <= 250 (1)

Software calibration time of both fitness trackers and smart rings:
6x + 2y <= 200
3x + y <= 100 (2)

Adding (1) & (2): 8x + 6y <= 350
40x + 30y <= 1750

So we know the max profit will be 1750. We can find an optimal pair of (x,y) to satisfy this equation, which is 25 & 25.

A certain electronics company produces and sells two products:
fitness tracker (X), Require 4 hours of assembly, 6 hours of Software, profit 40$
smart ring (Y), Requires 4 hours of Assembly, 4 hours of Software, Profit 30$

If the facility has limited weekly capacities for assembly and software calibration,

how many fitness trackers should the company produce each week to maximize profit for these two products?


(1) The cost of the components for each fitness tracker is twice that for each smart ring.
(we are not concerned about cost, as profit is already given) ,so A is insufficient


(2) The facility has the capacity for 200 hours of assembly time each week and 200 hours of software calibration each week.
4x+6y<=200-----------------Eq(1)
4x+4y<=200-----------------Eq(2)

maximum value for the profit 40x+30y (max), then we should keep X and Y close to each other for the maximum value of the expression
that means X=25, and Y=25 satisfy both equations and also maximizing the profit.

(yes, B is the answer Then)

To maximize the profits the company should not waste any time and produce maximum number of trackers and rings. For this since calibration of rings takes less time , we need to consider a number which is suitable for both trackers and rings (6hrs and 2 hrs) .Let x,y be number of FT and Rings respectively.

Option A does mention about costs which are irrevalent as profits for FT and Rings are already provided .
Option B gives two equations about Assembling and Calibration

4x+4y =200
6x+2y =200

Solving these two we get x=25,y=25 .
So to maximize profit we need produce 25 FT

Let x = number of fitness trackers produced
Let y = number of smart rings produced
Profit = 40x + 30y
Subject to:
4x + 4y <= 200 (assembly constraint)
6x + 2y <= 200 (calibration constraint)
x >= 0, y >= 0
Statement 1: The cost of components does not affect profit or constraints, so it is irrelevant.
Statement 2: 4x + 4y <= 200 and 6x + 2y <= 200 provide the key constraints.
From the assembly constraint:
4x + 4y = 200 => x + y = 50
From the calibration constraint:
6x + 2y = 200 => 3x + y = 100
Solve these two equations:
x + y = 50
3x + y = 100
Subtract the first from the second:
2x = 50 => x = 25
Substitute x = 25 into x + y = 50:
25 + y = 50 => y = 25
So, x = 25 and y = 25.
Answer: The company should produce 25 fitness trackers.
The correct answer is B.

Explanation:
  • We want to figure out how many fitness trackers to make each week to maximize profit, given:
    • Fitness tracker (F) needs 4 hours of assembly and 6 hours of calibration, a profit of $40 each.
    • Smart ring (R) needs 4 hours of assembly and 2 hours of calibration, profit of $30 each.
Statement (1): Tells us about component costs (a fitness tracker costs twice as much in components as a smart ring).
  • This alone does not give us any direct limit on production (no budget or cost constraint given), so it doesn’t tell us how many of each to make.
Statement (2): Tells us exactly how many hours of assembly (200) and calibration (200) we have each week.
  • From these time limits alone, we can set up constraints and solve a standard “maximize profit” problem (linear programming).
  • This is enough information to find the exact number of fitness trackers to produce.
Hence:
  • Statement (2) alone is sufficient to find how many fitness trackers maximize profit.
  • Statement (1) alone is not sufficient.
Therefore, the correct answer choice is:
B) Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient.

Since we know the assembly hours & software calibration hours along with the profit per item, to maximise profit each week - we need the total number of hours

i) From this, we get cost information but nothing about hours. Since we already know the profit margin, this is not required

INSUFFICIENT

ii) From this we get the hours for each i.e assembly hours & software calibration hours for the week.
Using different values, we can figure out the number of units of each type

SUFFICIENT
