Direction for questions 5-8: Go through the information given below and solve the questions based on it.
You are the Quality Control manager at a restaurant. Go through the case facts given below and solve the questions based on it:
Restaurant produces chicken nugget box (1,000 boxes at a time in a batch). Restaurant has to ensure that it does not supply undercooked nuggets (known as defective) to the customers. If a customer receives a defective nugget box, company has to pay a penalty of Rs. 150 per nugget box. To check the level of preparedness of nuggets, any of the two tests can be used:

Test 1

Test 2

Cost

Rs. 6 per nugget box

Cost

Rs. 9 per nugget box

Detection Rate

80%

Detection Rate

100%

Restaurant can re-cook the undercooked nuggets at a cost of Rs. 75 per nugget box. This box can be now sold to customer as it is now certainly properly cooked. All the boxes which are detected as defective must be re-cooked and after that, these boxes are properly cooked without any defect.

Let ‘x’ be the number of defective nugget boxes per batch.

Q5.      Manager should not use any quality control test, if it is expected that
(a) x < 100                   (b) 100 < x < 200        (c) x > 200                   (d) None of these

Q6.      If 200 < x < 400, then
(a) You should use Test 1                               (b) You should use Test 2      
(c) You can use Test 1 or Test 2                     (d) None of these

Q7.   If x = 1000, you should use
(a) Test 2   (b) Test 1 and Test 2   (c) Test 1 or No test   (d) None

Q8.   Company should be indifferent between Test 1 and No Test if it finds that the number of defective boxes is equal to
(a) 50                           (b) 100                         (c) 200                         (d) Not possible

Q1.      Sama lives as Bridge Street. Hence option (c) is the answer.
Q2.      House number 2 has blue colored door. Hence option (b) is the answer.
Q3.      It can be seen from the table that option (b) is the answer.
Q4.      As obvious from the above table, it can be determined for all three of them. Hence option (d) is the answer.

Solution to Questions 5 – 8:
Total cost = Cost of Testing + Re-cook charge + Penalty
It can be seen that if the number of defective nugget boxes per batch is very low, for example, 10, then it is better to pay the penalty on this, than to use any test.

Q5.      Total cost = Cost of Testing + Re-cook charge + Penalty
Using Test 1, total cost of testing = Rs. 6 × 1000 = Rs. 6000
Using options, at x = 100, Cost of Test 1 = Penalty paid for x = 100.
Using Test 1, Detection = 80 % of 100 = 80. These 80 will be reworked upon and for remaining 20, company will pay penalty.
Total cost = Cost of Testing + Re-cook charge + Penalty = Rs.6000 + 80 × Rs. 75 + 20 × Rs.  150 = Rs. 15,000.
For x = 100, penalty = Rs. 150 × 100 = Rs. 15000. Hence option (a) is the answer.

Q6.      Check for x = 300.

Total cost using Test 1:
Cost of testing = Rs. 6 × 1000 = Rs. 6000
Out of total defective 300 boxes, 80% will be detected. So, total detected boxes = 80% of 300 = 240 boxes. These 240 boxes will be reworked upon and remaining 60 boxes will go undetected. As per the rule, restaurant will have to pay penalty on these 60 boxes.
Re- cook charges = Rs. 75 × 240 = Rs. 18000
Penalty = Rs. 150 × 60 = Rs. 9000
So, total cost using Test 1 = Cost of Testing + Re-cook charge + Penalty = Rs.6000 + Rs. 18000 + Rs. 9000 = Rs. 33,000.

Total cost using Test 2:
Cost of testing = Rs. 9 × 1000 = Rs. 9000
Out of total defective 300 boxes, 100% will be detected. So, total detected boxes = 100% of 300 = 300 boxes. These 300 boxes will be reworked upon.
Re- cook charges = Rs. 75 × 300 = Rs. 22500
So, total cost using Test 2 = Cost of Testing + Re-cook charge + Penalty = Rs.9000 + Rs. 22500 + Rs. 0 = Rs. 31,500.
It can be seen that Total cost of Test 1 < Total cost of Test 2. Hence test 2 should be used. Hence option (b) is the answer.

Q7.      Option (a) is the answer.

Q8.      Using solution to Q(5),  Penalty for x = 100 is equal to Total cost of Test 1 for x = 100.

Hence answer is – No test or Test 1 if x = 100.

Hence option (b) is the answer.
