Show answer
Answer: A. KANB
Sort the letters of every option before choosing: they give PARK, RIVER, FOREST and BANK. Only then can the question be read, and BANK is the one it asks for.
Question 6 · Logical Reasoning
Which one is the odd one out?
- A.Pilot
- B.Ferry
- C.Helicopter
- D.Bicycle
Show answer
Answer: A. Pilot
Pilot belongs with people who do jobs; all the other words are ways to travel.
Question 7 · Logical Reasoning
The letters of RAINBOW stand in a line. What place is O from the right?
- A.7
- B.1
- C.6
- D.2
Show answer
Answer: D. 2
Count the letters first: RAINBOW has 7 of them, and O is letter 6 counting from the left. Place from the right = 7 − 6 + 1 = 2. The +1 is because the letter itself is counted too.
