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 = 116/2 = 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

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
head
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, ?

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       ?

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

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’)

ANKITA YADAV
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)
