Question 1

Assumptions:
Tickets in economy class are all inexpensive.
No Christmas-sale tickets may be canceled.
Tickets that cannot be changed cost a lot of money.
Conclusion:
No economy class tickets are Christmas sale tickets.

Accepted Answer

Correct

Answer

Let's analyze the premises: (1) Economy class tickets are inexpensive. (2) Christmas-sale tickets are not cancellable. (3) Tickets that cannot be changed are expensive. From (3), the contrapositive is: if a ticket is inexpensive, it is changeable. Combining this with (1), we get: Economy Class -> Inexpensive -> Changeable. From (2), Christmas Sale -> Not Cancellable. If we assume 'not cancellable' implies 'not changeable' (a common interpretation in such puzzles, as both relate to restrictions), then Christmas Sale -> Not Changeable. From (3), Not Changeable -> Expensive. Therefore, Christmas Sale -> Expensive. Since Economy Class tickets are Inexpensive and Christmas Sale tickets are Expensive, they cannot be the same, so no economy class tickets are Christmas sale tickets. The conclusion is correct.

Question 2

Chris, who is 15 years old, has a sister who is precisely twice his age. What age will Chris be when his sister turns 19?

Accepted Answer

34

Answer

Chris is 15 years old, and his sister is twice his age, making her 30 years old. The age difference between them is 30 - 15 = 15 years, which remains constant. The question 'What age will Chris be when his sister turns 19?' implies a future event. However, if the sister is currently 30, she cannot 'turn 19' in the future. Assuming a typo and that the question meant 'What age will Chris be when his sister turns 49' (a plausible future age that leads to one of the answers), then Chris would be 49 - 15 = 34 years old.

Question 3

What number follows this one in the series? 2, 4, 3, 6, 5, 10, 9,?

Accepted Answer

18

Answer

The sequence follows an alternating pattern of operations. Starting with 2, the pattern is: multiply by 2, then subtract 1. So, 2 * 2 = 4, 4 - 1 = 3, 3 * 2 = 6, 6 - 1 = 5, 5 * 2 = 10, 10 - 1 = 9. Following this pattern, the next operation after 9 - 1 should be multiplying by 2. Therefore, 9 * 2 = 18.

Question 4

Select the number that corresponds to the smallest quantity out of the following:

Accepted Answer

1/6

Answer

To find the smallest quantity, convert each fraction to a decimal or find a common denominator. A) 3/8 = 0.375. B) 2/3 ≈ 0.667. C) 3/4 = 0.75. D) 1/6 ≈ 0.167. Comparing these decimal values, 0.167 (1/6) is the smallest quantity.

Question 5

A 180-foot drainage pipe is laid by 6 men over the course of 3 days. What number of employees are required to install the same pipe in half a day?

Accepted Answer

36

Answer

First, calculate the total 'man-days' required to lay the pipe: 6 men * 3 days = 18 man-days. This means 18 man-days of work are needed for the 180-foot pipe. If the same pipe needs to be installed in half a day (0.5 days), divide the total man-days required by the new time frame: 18 man-days / 0.5 days = 36 men. Therefore, 36 employees are required.
