Here, KN ⇒ K(11) + N(14) = 25,
LM ⇒ L(12) + M(13) = 25, place value of Y = 25 and place value of X = 24 Hence X is ODD from others.

8. Find the ODD one out from the given options. [RRB JE 30/05/2019 (Afternoon)]

Correct Answer: (b) 29-82
Solution:

Pattern follows :-
⇒ 36 - 27 ⇒ 3 + 6 = 9, 2 + 7 = 9
⇒ 23 - 14 ⇒ 2 + 3 = 5, 1 + 4 = 5
⇒ 18 - 45 ⇒ 1 + 8 = 9, 4 + 5 = 9
⇒ 29 - 82 ⇒ 2 + 9 = 11, 8 + 2 = 10
Hence 29 - 82 is ODD one from the others.

9. Find the ODD one out from the given options. [RRB JE 28/06/2019 (Evening)]

Correct Answer: (d) 49-169
Solution:

25 - 81 ⇒ 5² - 9²
36 - 100 ⇒ 6² - 10²
16 - 64 ⇒ 4² - 8²
49 - 169 ⇒ 7² - 13² (Here both 7 and 13 is prime number hence this pair is ODD from others.)
