Explanation
The series is increasing by 8 each time. Starting from 3, adding 8 gives 11, then adding 8 again gives 19, and so on. Therefore, the missing number at the end of the series should be 27 + 8 = 35.
2.
Identify the missing number at the END of the series.
3, 6, 11, 18, ?
Correct Answer
D. 27
Explanation
The pattern in the series is that each number is obtained by adding consecutive odd numbers starting from 1. The first number is 3, obtained by adding 1 to 2. The second number is 6, obtained by adding 1 to 5. The third number is 11, obtained by adding 1 to 10. The fourth number is 18, obtained by adding 1 to 17. Therefore, the missing number at the end of the series would be obtained by adding 1 to 18, resulting in 19. However, this number is not given as an option. The closest option is 27, which is obtained by adding 1 to 26.

516, 497, 478, 459, ?
Correct Answer
B. 440
Explanation
The given series is decreasing by 19 in each step. Therefore, to find the missing number at the end of the series, we subtract 19 from the previous number. 459 - 19 = 440.
4.
Identify the missing number at the END of the series.316, 323, 332, 343, ?
Correct Answer
A. 356
Explanation
The series follows a pattern where each number is obtained by adding the square of the previous number to it. Starting from 316, the next number is obtained by adding the square of 316 to it (316 + 316^2 = 316 + 99856 = 100172). Continuing this pattern, the missing number at the end of the series is obtained by adding the square of 343 to it (343 + 343^2 = 343 + 117649 = 117992). Therefore, the missing number is 356.
5.
Identify the missing number at the END of the series.662, 645, 624, 599, ?
Correct Answer
E. 570
Explanation
The series is decreasing by a certain number each time. The difference between the first two numbers is 17, the difference between the second and third numbers is 21, and so on.

It costs a manufacturer X Euros per component to make the first 1,000 components. All subsequent components cost X/3 each.When X = €1.50, how much will it cost to manufacture 4,000 components?
Correct Answer
B. 3,000
Explanation
The cost per component for the first 1,000 components is X Euros, which is €1.50. Therefore, the cost to manufacture the first 1,000 components is 1,000 * €1.50 = €1,500.
For all subsequent components, the cost per component is X/3, which is €1.50/3 = €0.50.
To manufacture the remaining 3,000 components, it will cost 3,000 * €0.50 = €1,500.
Adding the cost of the first 1,000 components to the cost of the remaining 3,000 components, the total cost to manufacture 4,000 components is €1,500 + €1,500 = €3,000.

Anna
and John both drive to their new home 400 km away. Anna drives the family car at
an average speed of 60 km/h. John drives the removal truck at an average speed
of 50 km/h. During the journey, Anna stops for a total of 1 hour and 20 minutes
while John stops for half as long.
What
is the difference in minutes between their arrival times?
Correct Answer
C. 40
Explanation
Anna's total driving time can be calculated by dividing the distance by her average speed: 400 km / 60 km/h = 6.67 hours. Since she stops for 1 hour and 20 minutes (1.33 hours), her total travel time is 6.67 hours + 1.33 hours = 8 hours.
Similarly, John's total driving time can be calculated by dividing the distance by his average speed: 400 km / 50 km/h = 8 hours. Since he stops for half as long as Anna, his total travel time is 8 hours + (1.33 hours / 2) = 8.67 hours.
The difference in their arrival times can be calculated by subtracting Anna's total travel time from John's total travel time: 8.67 hours - 8 hours = 0.67 hours. Since there are 60 minutes in an hour, the difference is 0.67 hours * 60 minutes/hour = 40.2 minutes, which can be rounded to 40 minutes. Therefore, the correct answer is 40.

A
total of 800 copies of a CD were sold. 60% were sold at a 50% discount, 20%
were sold at a 30% discount and the remainder were sold at the full price of €8,95.
What
was the approximate total revenue in Euros?
Correct Answer
B. 4,579
Explanation
Approximately 60% of 800 copies were sold at a 50% discount, which means 480 copies were sold at a discounted price. Similarly, 20% of 800 copies were sold at a 30% discount, which means 160 copies were sold at a discounted price. The remaining copies, which is 20% (160 copies), were sold at the full price of €8.95. To calculate the revenue, we need to multiply the number of copies sold at each price by their respective prices and then add them together. The revenue from the copies sold at a 50% discount is approximately €8.95 * 0.5 * 480 = €2,151.60. The revenue from the copies sold at a 30% discount is approximately €8.95 * 0.7 * 160 = €2,255.20. The revenue from the copies sold at the full price is approximately €8.95 * 160 = €1,432. Adding all these revenues together, we get approximately €2,151.60 + €2,255.20 + €1,432 = €4,838.80. Therefore, the approximate total revenue in Euros is €4,838.80, which is closest to the given answer of 4,579.

A driver drives 8 km South then 6 km W. and 2 km S. again. She then drives 3 km E. to avoid a traffic jam before driving 6 km N. How many kilometres is she from her starting point?
Correct Answer
B. 5
Explanation
The driver initially drives 8 km south, then 6 km west, and 2 km south again. This means she has traveled a total of 8 + 2 = 10 km south. She then drives 3 km east, which cancels out 3 km of her westward travel. Finally, she drives 6 km north, which cancels out 6 km of her southward travel. Therefore, she is left with a net distance of 10 km south - 3 km west + 6 km north = 13 km - 3 km = 10 km. Since she started 10 km south of her starting point, she is 10 km away from her starting point.

An aircraft flies 930 miles in 75 minutes. How many miles does it fly in 4 hours 45 minutes assuming a constant speed?
Correct Answer
E. 3534
Explanation
Assuming a constant speed, we can use the formula distance = speed × time. In this case, the aircraft flies 930 miles in 75 minutes. To find the distance it flies in 4 hours 45 minutes (which is equal to 285 minutes), we can set up a proportion: 930 miles / 75 minutes = x miles / 285 minutes. Solving for x, we find that the aircraft flies 3534 miles.
