There is a desk that can hold at most four (4) files. On this desk, six (6) files A through F are used for a job. When the fifth file needs to be put on the desk, the file with the longest time since the last use among the four (4) will be put in a drawer. If the files are put on the desk and referenced in order of A, B, C, D, E, C, B, D, F, B, which of the following is the last file to be put in the drawer?

At a certain company, employees get a medical allowance equal to 5% of their monthly base salary in addition to their monthly base salary. If the total of the monthly base salary and medical allowance is more than 5,000, a 20% tax is deducted from the total. In the program below, the function calculateTotalSal receives the monthly base salary as an argument and returns the monthly total salary after tax deduction. Which of the following is the correct combination of pieces of code to be inserted into [A] and [B] in the program? Here, the monthly base salary is a multiple of 100. [Program] O integer: calculateTotalSal(integer: monthlyBaseSal) integer: monthlyTotalSal monthlyTotalSal <- integer part of (monthlyBaseSal x 1.05) if (monthlyTotalSal > [A]) monthlyTotalSal <- integer part of (monthlyTotalSal x [B]) endif return monthlyTotalSal

In the program below, the function subTotal receives an integer array inputarr as an argument, returns an array arr in which the sum of all elements of original array inputarr up to that location is stored in the same location. Which of the following is the correct combination of pieces of code to be inserted into [A] and [B] in the program? Here, the size of the array inputarr is greater than 1, elements outside the bounds of the array must not be accessed, and the array index starts at 1. [Program] O integer []:subTotal(integer []: inputarr) integer: i integer: n <- the number of elements in inputarr integer []: arr <- {0, ..., 0} // Number of elements is n. arr[1] <- inputarr[1] for (increase i from [A] to n by 1) arr[i] <- inputarr[i] + [B] endfor return arr

The system configurations A through C are made up by connecting multiple identical devices. Which of the following is the list where A through C are sorted in descending order of availability? Here, the parallel connection requires only one (1) of the devices to be functional, while the series connection requires all devices to be functional. A: Two devices connected in series. B: One device in series, followed by two devices in parallel. C: Three devices all connected in parallel.

Spreadsheet software is used to predict sales according to the weather. The probability for the weather type (sunny, cloudy, rainy) on the day to be predicted and the predicted sales amount by weather type for each product are entered into the worksheet below. An expression is entered in cell E4 to calculate the predicted sales amount on the day for Product A, and this is copied to cells E5 through E6 and used. Which of the following is the appropriate expression to be entered in cell E4? [Worksheet] A B(Sunny) C(Cloudy) D(Rainy) Row2 Probability 0.5 0.3 0.2 Row4 Product A 300,000 100,000 80,000 Row5 Product B 250,000 280,000 300,000 Row6 Product C 100,000 250,000 350,000

When the system development activities are carried out, a plan is set up to complete the activities in 20 days by six (6) members having the same productivity. However, the plan is changed to have the activities finished in 15 days, and new members are added. When the productivity of the new members is half of the initially planned members, what is the minimum number of new members necessary for finishing the activities in 15 days?

The PC on one's desk and the printer in a shared space are started by a single person. Movement between desk and printer takes 60 seconds one way. Each operation/processing is sequential, but during automatic processing of one device, the person can move or operate the other device in parallel. What is the minimum time (in seconds) for the person to start PC startup at desk, move, start and end printer startup, return to desk, and end PC startup? PC startup sequence: A: Turn on power - 3 sec (Manual) B: Login screen startup - 150 sec (Automatic) C: Login operation - 10 sec (Manual) D: Application startup after login - 60 sec (Automatic) Printer startup sequence: E: Turn on power - 3 sec (Manual) F: Startup - 60 sec (Automatic)

The entire inventory of Warehouse A and Warehouse B is to be sent to Store C and Store D. The number of items in the inventory of Warehouse A and Warehouse B is 35 and 15 respectively, and the required number of items for Store C and Store D is 20 and 30 respectively. The shipment cost for each item is: Store C Store D Warehouse A $400 $200 Warehouse B $200 $100 Under these conditions, what is the minimum total shipment cost in dollars?

The sales and the costs for a certain product for this month are as shown below. When the unit sales price is changed from 1,000 yen to 800 yen, in order to avoid making a loss, at least how many units need to be sold each month? Here, the fixed cost and the variable cost per unit of the product do not change. Sales amount: 2,000,000 yen Unit sales price: 1,000 yen Units sold: 2,000 Fixed cost: 600,000 yen Variable cost per unit: 700 yen

The table below shows the evaluated scores of the proposals of four (4) vendors from the viewpoints of management, technology, and price. When each score is weighted and the vendor with the highest total score is selected as the supplier, which of the following vendors is selected?
