In a recent tender, X people participated. 35% of the X people, who made an offer won the specific tender they participated in. 70% of the rest, were disappointed from the result of the tender. Which of the following expressions represents the number of people who weren’t disappointed although they didn’t win the tender?

  1. 39X/200.
  2. 25X/50.
  3. 19.5X/200.
  4. 35X/250.
  5. 90X/200.

Answer(s): A

Explanation:

65X/100 is the number of people who didn’t win the tender. 30% of that number is the number of people who weren’t deeply disappointed about the fact that they didn’t win. 30 x (65X/100) /100 = 19.5/100 = 39/200. The correct answer is A.



What is 0.01 x 5 x 0.03 in terms of percent?

  1. 15%
  2. 1.5%
  3. 0.15%
  4. 0.015%
  5. 0.0015%

Answer(s): C

Explanation:

Since 0.01 and 0.03 each have 2 decimal places, their product must have 4 (2 + 2) decimal places. Because 1 x 3 x 5 is 15, you need to add 2 zeros to get the correct number of decimal places, so the product of 0.01, 5 and 0.03 is 0.0015. To change a decimal to a percentage you multiply by 100 and move the decimal point 2 places to the right, so 0.0015 is 0.15%. The correct answer is C.



In a barrel of juice there is 30 liters; in a barrel of beer there are 80 liters. If the price ratio between barrels of juice to a barrel of beer is 3:4, what is the price ratio between one liter of juice and one liter of beer?

  1. 3:2.
  2. 2:1.
  3. 3:1.
  4. 4:3.
  5. 3:4.

Answer(s): B

Explanation:

Pick numbers: a barrel of beer costs $40 and a barrel of juice costs $30 according to the given ratio. One liter of beer will cost $0.5 and one liter of juice will cost $1. Therefore, the price ratio is 2:1. The correct answer is B.



From the starting point in a boat race, one competitor started to sail north at a speed of 1.6 Km/h, the other competitor started to sail west at a speed of 1.2 Km/h. What is the distance in Km between the two competitors after 5 hours?

  1. 10.
  2. 12.
  3. 12.5.
  4. 14.
  5. 15.4.

Answer(s): A

Explanation:

One is going north and the other is going west. The distance can be calculated using the Pythagorean theorem. One made a distance of 1.6 x 5 = 8 Km, The second one did 1.2 x 5 = 6 Km. The distance between them is the square root of (64 + 36) = 10 Km. The best answer is A.
