Question 1

A data file is transferred over a network. Was the transfer completed in under one minute? (1) The file size is 60 MB. (2) The network speed is 1 MB per second.

Accepted Answer

Both statements together are sufficient, but neither alone is sufficient

Answer

Transfer time = 60 MB ÷ 1 MB/s = 60 seconds, which is exactly one minute, not under it; both statements are needed to determine this.

Question 2

Is integer k a multiple of 12? (1) k is a multiple of 4. (2) k is a multiple of 3.

Accepted Answer

Both statements together are sufficient, but neither alone is sufficient

Answer

12 = 4 × 3 and gcd(4,3)=1, so being a multiple of both 4 and 3 means k is a multiple of 12.

Question 3

What is the selling price of an item? (1) The cost price of the item is $40. (2) The item is sold at a 25% profit.

Accepted Answer

Both statements together are sufficient, but neither alone is sufficient

Answer

Selling price = $40 × 1.25 = $50; you need the cost and the profit percentage together.

Question 4

In a sorted list of numbers, is the median greater than the mean? (1) The list is: 2, 3, 4, 8, 8. (2) The list contains five numbers.

Accepted Answer

Statement 1 alone is sufficient

Answer

With the full list given in statement 1, median = 4 and mean = 5, so median < mean; statement 1 alone is sufficient to answer the question.

Question 5

Can an employee complete a task alone in 8 hours? (1) Working together, two employees finish the task in 3 hours. (2) Employee B alone takes 12 hours to complete the task.

Accepted Answer

Both statements together are sufficient, but neither alone is sufficient

Answer

Using the combined rate formula: 1/A + 1/12 = 1/3 → A = 4 hours; both statements are needed.
