Odd One Out – Railway Reasoning part – II

(a) 324 – 19 = 18² – 18 + 1
(b) 625 – 26 = 25² – 25 + 1
(c) 441 – 22 = 21² – 21 + 1
(d) 144 – 15 = 12² ≠ 12 + 1

In (17, 303) ⇒ 17² + 14 = 303
In (8, 82) ⇒ 8² + 14 = 82
In (24, 590) ⇒ 24² + 14 = 590
In (19, 375) ⇒ 19² + 14 = 375

We can clearly see in the above expression that all three follow the same logic except (8, 82).

In GEM ⇒ G - 2 = E, E + 8 = M
In JHQ ⇒ J - 2 = H, H + 9 = Q
In YWE ⇒ Y - 2 = W, W + 8 = E
In KIQ ⇒ K - 2 = I, I + 8 = Q

We can clearly see in the above expression that all follow the same logic except JHQ

In (3, 12), ⇒ 3 × (3 + 1) = 12
In (14, 220), ⇒ 14 × (14 + 1) ≠ 220
In (11, 132), ⇒ 11 × (11 + 1) = 132
In (5, 30), ⇒ 5 × (5 + 1) = 30

We can clearly see in the above expression that all three follow the same logic except (14, 220).

In (18, 52), ⇒ 18 × 3 - 2 = 52
In (24, 70), ⇒ 24 × 3 - 2 = 70
In (43, 86), ⇒ 43 × 3 - 2 ≠ 86
In (39, 115), ⇒ 39 × 3 - 2 = 115

We can clearly see in the above expression that (43, 86) is an odd one.

In KNF, ⇒ K + 3 = N, N - 8 = F
In PSL, ⇒ P + 3 = S, S - 7 = L
In JMF, ⇒ J + 3 = M, M - 7 = F
In UXQ, ⇒ U + 3 = X, X - 7 = Q

We can clearly see that KNF is an odd one.

In (2, 5) ⇒ 2² + 2/2 = 5
In (4, 18) ⇒ 4² + 4/2 = 18
In (6, 39) ⇒ 6² + 6/2 = 39
In (8, 66) ⇒ 8² + 8/2 ≠ 66

So we can clearly see that (8, 66) is an odd one.

Out of the four given number pairs three are alike,
12 - 96 → (12 × 8 = 96)
15 - 120 → (15 × 8 = 120)
13 - 104 → (13 × 8 = 104)
But for 16 - 118 → (16 × 8 ≠ 118)

Out of the four number - pair listed three are alike,
4 - 64 → (4³ = 64)
6 - 216 → (6³ = 216)
9 - 729 → (9³ = 729)
But, in 7 - 27 → (7³ ≠ 27)

Out of the four sports listed, the process of the three sports → Discus throw, Shot - put, Hammer throw are alike. But Golf is a completely different sport.
