# QUESTIONS ON REASONING (PART-9)

#### QUERY 161

Pick the odd one out
Tiger
Lion
Leopard
Wolf

MAHA GUPTA
WOLF (option ‘4’). All other are animals of cat family, whereas WOLF is of dog family.

#### QUERY 162

Mountain : Hill :: Tree : ?

Ground
Leaf
Forest
Shrub

MAHA GUPTA
SHRUB (option ‘4’). MOUNTAIN = a very high hill. HILL = an area of land that is higher than the land, but not as high as a mountain. So similar is the relation between tree and shrub.

#### QUERY 163

2     6      18
4   10     30
3    8       ?

24
36
17
30

MAHA GUPTA
Every last number in each column is half the sum of the first two; see how
(2 + 4)/2 = 3
(6 + 10)/2 = 8

So the required number
(18 + 30)/2 = 24 (option ‘1’)

#### QUERY 164

92*24 = 58
16*56 = 36
33*49 = 41
32*84 = ?

56
66
52
58

MAHA GUPTA
Half the sum of the numbers on LHS to get RHS; see how
(92 + 24)/2 = 126/2 = 58
(16 + 56)/2 = 72/2 = 36
(33 + 49)/2 = 82/2 = 41

Therefore the required number
(32 + 84)/2 = 116/2 = 58 (option ‘4’)

#### QUERY 165

2, 8, 26, 48, ?

82
72
78
98

CHETAN SHARMA
Pattern
1^2 + 1 = 2
3^2 – 1 = 8
5^2 + 1 = 26
7^2 – 1 = 48

So the required number
9^2 + 1 = 82 (option ‘1’)

#### QUERY 166

summit : apex :: summon : ?

judge
court
beckon
none of these

MAHA GUPTA
BECKON (option ‘3’). Words on LHS are synonyms, SUMMON and BECKON are two such words.

#### QUERY 167

heart : pericardium :: brain : ?

bones
skull
cranium

MAHA GUPTA
CRANIUM (option ‘D’). PERICARDIUM is protective cover of the HEART; so is CRANIUM for BRAIN.

#### QUERY 168

52*9 = 8
36*8 = 30
25*6 = 20
then
48*9 = ?

MAHA GUPTA
Multiply the unit digit of the number in each row with the difference of the rightmost number on LHS and tens digit of the other number; see how
2*(9 – 5) = 8
6*(8 – 3) = 30
5*(6 – 2) = 20

Therefore the required number
8*(9 – 4) = 40

#### QUERY 169

0, 2, 8, 14, ?, 34

20
23
24
none

SHIV KISHOR
1^2 – 1 = 0
2^2 – 2 = 2
3^2 – 1 = 8
4^2 – 2 = 14
5^2 – 1 = 24 (option ‘3’)
6^2 – 2 = 34

#### QUERY 170

28 , 38, 49, 62, 70, 77, ?

90
91
88
69

MAHA GUPTA
Every next number is more than the sum of the digits of its previous number, see how
28 + (2 + 8) = 38
38 + (3 + 8) = 49
49 + (4 + 9) = 62
62 + (6 + 2) = 70
70 + (7 + 0) = 77

Therefore the required number
77 (7 + 7) = 91 (option ‘2’)

#### QUERY 171

5, 3, 3, 5, 15, ?

60
66
72
69

KUMAR SAURABH
Pattern
5*1 – 2 = 3
3*2 – 3 = 3
3*3 – 4 = 5
5*4 – 5 = 15

Therefore the required number
15*5 – 6 = 69 (option ‘4’)

#### QUERY 172

human : mind :: ? : CPU

computer
motherboard
processor
none

MAHA GUPTA
MIND does same work for human as CPU for computer. So the correct option is ‘1’.

#### QUERY 173

321, 301, ?, 181, 21

281
161
241
261

MAHA GUPTA
Pattern
321 – 20 = 301
301 – 40 = 261 (option ‘4’)
261 – 80 = 181
181 – 160 = 21

#### QUERY 174

45*35*30*25 = 27
20*40*30*60 = 30
40*35*65*25 = ?

36
33
45
60

MAHA GUPTA
Divide every number on LHS by 5 and add all, see how
45/5 + 35/5 + 30/5 + 25/5 = 27
20/5 + 40/5 + 30/5 + 60/5 = 30

Therefore the required number
40/5 + 35/5 + 65/5 + 25/5 = 33 (option ‘2’)

#### QUERY 175

Find odd number
162
405
567
644

ANURAG PAL
Pattern
16/2 = 8
56/7 = 8
40/5 = 8

But here in 644 as 64/4 = 16, so it’s the answer (option ‘4’)

#### QUERY 176

165     234     131,
220    468    248,
533    791       ?

320
274
262
132

MAHA GUPTA
The rightmost number in each row is the result of subtraction from bigger digits from the smaller ones at same places, see how
2 – 1 = 1, 6 – 3 = 3, 5 – 4 = 1; so the rightmost number = 131
4 – 2 = 2, 6 – 2 = 4, 8 – 0 = 8, so the rightmost number = 248

Therefore the required number
7 – 5 = 2, 9 – 3 = 6, 3 – 1 = 2; 262 (option ‘3’)

#### QUERY 177

15 5 2 6 = 80
9 4 7 6 = 65
13 11 16 8 = ?

48
72
35
120

ANSUMAN SINGH
(15 – 5)*(6 + 2) = 80
(9 – 4)*(7 + 6) = 65
Therefore the required number
(13 – 11)*(16 + 8) = 48 (option ‘1’)

#### QUERY 178

0, 4, 8, 24, 64, 176, ?

180
480
280
300

MAHA GUPTA
Starting from third term each is twice the sum of its previous two, see how
(0 + 4)*2 = 8
(4 + 8)*2 = 24
(8 + 24)*2 = 64
(24 + 64)*2 = 176

So the required number
(64 + 176)*2 = 480 (option ‘2’)

#### QUERY 179

1356 : 21 :: 4621 : x

23
44
49
50

Add the last to the product of the first three, see how
(1*3*5) + 6 = 21

So the required number
(4*6*2) + 1 = 49 (option ‘3’)

#### QUERY 180

124, 112, 176, 420, 1488, ?

SHIV KISHOR
124*1 – 12*(1^2) = 112
112*2 – 12*(2^2) = 176
176*3 – 12*(3^2) = 420
420*4 – 12*(4^2) = 1488
1488*5 – 12*(5^2) = 7140 (answer)
