66. Choose the correct option from the following:Dog: Bark :: Goat : ?
(A) Bleat
(B) Howl
(C) Grunt
(D) Bray
Answer:
(A) Bleat
Explanation:
This is an animal-to-vocalization analogy. The sound a dog makes is called a bark, while the wavering cry a goat (or sheep) makes is called a bleat.
67. Choose the correct option from the following :Cattle: Herd :: Sheep:?
(A) Flock
(B) Swarm
(C) Crowd
(D) Shoal
Answer:
(A) Flock
Explanation:
This is an animal-to-collective-noun analogy. A group of cattle is collectively called a herd, and a group of sheep is collectively called a flock.
68. Fill in the next number in the series :16, 26, 37, 49, 62, ____________
(A) 72
(B) 76
(C) 65
(D) 66
Answer:
(B) 76
Explanation:
Look at the differences between the consecutive terms: $26 – 16 = 10$; $37 – 26 = 11$; $49 – 37 = 12$; $62 – 49 = 13$. The difference incrementally increases by 1 each time. The next difference must be 14. So, $62 + 14 = 76$.
69. Fill in the next number in the series :15, 13, 10, 8, 5, 3, ____________
(A) 2
(B) 4
(C) 0
(D) 1
Answer:
(C) 0
Explanation:
The pattern alternates between subtracting 2 and subtracting 3. $15 – 2 = 13$; $13 – 3 = 10$; $10 – 2 = 8$; $8 – 3 = 5$; $5 – 2 = 3$. Therefore, the next step is to subtract 3: $3 – 3 = 0$.
70. Find the next number in the series :1, 2, 9, 28, 65, ____________
(A) 126
(B) 182
(C) 196
(D) 245
Answer:
(A) 126
Explanation:
This series relies on cubes of whole numbers plus one ($n^3 + 1$). $0^3 + 1 = 1$; $1^3 + 1 = 2$; $2^3 + 1 = 9$; $3^3 + 1 = 28$; $4^3 + 1 = 65$. The next term is $5^3 + 1 = 125 + 1 = 126$.
