Logic Questions and Answers

Answer: A

Correct answer: JAK

The first letters advance by one through the series: F, G, H, I, so the next is J. The middle letter is A throughout. The last letters run G, F, I, H, so they advance by two and alternate high and low within each pair; the pair beginning with J takes K. The answer is therefore JAK.

Answer: D

Correct answer: KLLA

Take the four positions separately. The first letters go E, G, I, ?, M, advancing by two, so the missing one is K. The second is L throughout and the fourth is A throughout. The third letters go F, H, J, ?, N, also advancing by two, so the missing one is L. That gives KLLA.

Answer: B

Correct answer: ASACFX

Compare LIVING with KGSHLD letter by letter: L to K is minus one, I to G minus two, V to S minus three, and then the cycle repeats, I to H minus one, N to L minus two, G to D minus three. Applying the same cycle to BUDDHA gives B minus one is A, U minus two is S, D minus three is A, D minus one is C, H minus two is F, and A minus three wraps to X.

Answer: A

Correct answer: Daughter in law

Suresh and Amar are both sons of Mahesh, being brothers. Jia is married to Amar, so Jia is the wife of one of Mahesh’s sons, which makes her his daughter-in-law. Sia, her sister, is the wife of the other son and stands in exactly the same relation to Mahesh.

Answer: B

Correct answer: Father-in-law

Work inward from the description. Smith’s sister’s mother is Smith’s own mother. Her grandson, on Smith’s side of the family, is Smith’s son. Lilly is that son’s wife, so Smith is her husband’s father - her father-in-law.

Answer: D

Correct answer: Soles

The question asks what a shoe must have by definition rather than what it commonly has. Laces, leather and straps all appear on some shoes and not others - a slip-on has no laces, a canvas shoe no leather. A sole is what makes the object a shoe at all, so it is the only universal.

Answer: C

Correct answer: Peter’s team

Take the comparisons in turn. Peter beats David; Smith beats Peter; Smith beats Taiwa; and Taiwa scores less than David. That gives Smith above Peter above David above Taiwa, a complete ordering. Second in descending order is therefore Peter’s team.

Answer: D

Correct answer: Sonam

David is below Dechen and above Sonam, and Karma is above David. So Dechen and Karma are both above David and Sonam is the only one below him. The ordering is not complete - nothing settles whether Dechen or Karma is higher - but the bottom position is determined, and it is Sonam’s.

Answer: C

Correct answer: between Peter and Kenel

Chumley and Senthil take the two ends. Chumley must sit next to Peter, so Peter is in the second seat. Donald may not sit next to Senthil, so he cannot take the fourth seat and must take the third. Kenel must sit next to Donald, and the only seat left is the fourth. The order is Chumley, Peter, Donald, Kenel, Senthil.

Answer: D

Correct answer: 3, 5, 1, 4, 2

The sequence follows the natural order of cause and effect. Study comes first, then the exam that tests it, then the job the qualification obtains, then the income the job brings, and finally the independence the income makes possible. Each step is the precondition of the one after it.
