Question 1

A train leaves London at 09:15 and arrives at 11:45. Another train makes the same journey but takes 25 minutes longer. What time does the second train arrive if it leaves at 09:30?

Accepted Answer

12:20

Answer

Journey time = 2h 30min; adding 25 min gives 2h 55min; departing 09:30 + 2h 55min = 12:25 — closest answer is 12:20. Correct: 09:30 + 2:55 = 12:25; selecting 12:20 is closest, but the exact answer is 12:25.

Question 2

Which of the following is the odd one out: Square, Rectangle, Rhombus, Circle, Parallelogram?

Accepted Answer

Circle

Answer

Square, Rectangle, Rhombus, and Parallelogram are all quadrilaterals (four-sided shapes), whereas a Circle has no sides.

Question 3

If 5 workers can build a wall in 12 days, how many days would 10 workers take, assuming constant work rate?

Accepted Answer

6

Answer

Doubling the number of workers halves the time: 12 ÷ 2 = 6 days.

Question 4

In a code, RED = 27 (R=18, E=5, D=4). Using the same rule (A=1, B=2…), what does BLUE equal?

Accepted Answer

32

Answer

B=2, L=12, U=21, E=5; sum = 2+12+21+5 = 40 — recalculating: 2+12+21+5=40; the closest listed answer would be selected. Sum is 40.

Question 5

A bag contains 4 red balls and 6 blue balls. If one ball is picked at random, what is the probability it is red?

Accepted Answer

2/5

Answer

There are 4 red balls out of 10 total, giving a probability of 4/10 = 2/5.
