Looking at the alphabetical positions: A(1), C(3), E(5), J(10), O(15). The gaps progressively change, or alternatively, this sequence is meant to represent vowels interleaved with a mathematical increment. However, a more standard reasoning test logic maps this sequence’s continuation to ‘U’.
67. 7, 3, 10, 6, 16, ________, 24
(A) 9
(B) 8
(C) 7
(D) 6
Answer:
(B) 8
Explanation:
This is a sequence where every third number is the sum of the two preceding numbers. $7 + 3 = 10$. Then the next pair is $10$ and $6$, where $10 + 6 = 16$. The next pair starts with $16$ and an unknown number that must sum to $24$. Therefore, $16 + 8 = 24$. The missing number is 8.
68. In a certain language ‘FEBRUARY’ is coded as RYUABRFE, then which would be written as ERMBVENO in that language
(A) FEBRUARY
(B) JANUARY
(C) NOVEMBER
(D) DECEMBER
Answer:
(C) NOVEMBER
Explanation:
The coding logic splits the word into consecutive two-letter pairs and reverses the order of those pairs. FE-BR-UA-RY becomes RY-UA-BR-FE. Applying this in reverse to decode ER-MB-VE-NO, we restore the pairs from right to left: NO-VE-MB-ER, which spells NOVEMBER.
69. A family has a man, his wife, their four sons and their wives. The family of every son also has 3 sons and one daughter. Find out the total number of male members in the whole faimly
(A) 4
(B) 8
(C) 12
(D) 17
Answer:
(D) 17
Explanation:
Count only the males: The original man (1) + his four sons (4) + the grandsons from the four sons ($4 \times 3 = 12$). Total male members = $1 + 4 + 12 = 17$.
70. What should come in place of question mark?MAMTA: REPVB:: PUNAM:?
(A) NCQYU
(B) UYQCN
(C) UZSFR
(D) RFSZU
Answer:
(B) UYQCN
Explanation:
The coding shifts each letter forward by a decreasing increment: +5, +4, +3, +2, +1. M(+5)=R, A(+4)=E, M(+3)=P, T(+2)=V, A(+1)=B. Applying to PUNAM: P(+5)=U, U(+4)=Y, N(+3)=Q, A(+2)=C, M(+1)=N. The result is UYQCN.
