15 Java programmers, working in a constant pace, finish a web page in 3 days. If after one day, 9 programmers quit, how many more days are needed to finish the remainder of the job?

  1. 5.
  2. 2.
  3. 8.
  4. 4.
  5. 6.

Answer(s): A

Explanation:

The total working days for finishing a web page are (15 x 3) 45. If after one day 9 programmers quit, only 15 working days are done and the rest of the programmers (6) Need to finish (45 – 15) 30 days of work. It will take them 5 more days.



Tim and Élan are 90 miles away from one another. They are starting to move towards each other simultaneously, Tim at a speed of 10 Mph and Élan at a speed of 5 Mph. If every hour they multiply their speeds, what is the distance that Tim will pass until he meets Élan?

  1. 30 miles.
  2. 35 miles.
  3. 45 miles.
  4. 60 miles
  5. 65 miles

Answer(s): D

Explanation:

Tim is traveling at twice the speed of Élan, and so will be after they multiply their speeds.
In other words, their speeds will always be at a 2:1 ratio no matter what and therefore the ratio between the roads that they’ll pass will also be 2:1 or 60 miles to 30 miles. Tim will go through 60 miles.



In a rectangular coordinate system, what is the area of a triangle whose vertices have the coordinates (4, 0), (6, 3), and (6, -3)?

  1. 7.5
  2. 7
  3. 6.5
  4. 6
  5. 5.5

Answer(s): D

Explanation:

First draw the x and y-axes, then plot the points and connect them. The length of the base is 6 units [from (6, 3) to (6, -3)] and the height is 2 units [from (6, 0) to (4, 0)].
Area of a triangle = (base × height) / 2, so (6 × 2)/2 is 6.



For every X, the action [X] is defined: [X] is the greatest integer less than or equal to X. What is the value of [6.5] x [2/3] + [2] x 7.2 + [8.4] – 6.6?

  1. 12.6.
  2. 14.4.
  3. 15.8.
  4. 16.2.
  5. 16.4.

Answer(s): C

Explanation:

[6.5] x [2/3] + [2] x 7.2 + [8.4] – 6.6 = 6 x 0 + 2 x 7.2 + 8 - 6.6 = 15.8
