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.

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’)

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’)

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

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

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’)

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

computer
motherboard
processor
none
MAHA GUPTA
MIND does same work for human as CPU for computer. So the correct option is ‘1’.

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’)

ANURAG PAL
Pattern
16/2 = 8

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’)

ANSUMAN SINGH
(15 – 5)*(6 + 2) = 80
(9 – 4)*(7 + 6) = 65
Therefore the required number

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’)
