RED = DER = 4/5/18; on adding 2 to each = 6/7/20 = 6720
GREEN = NEERG = 14/5/5/18/7; adding 2 to each =16/7/7/20/9 = 1677209 (option ‘1’)

The given sequence can be bifurcated in two sequences; one sequence of numbers at odd places and the other sequence of numbers at even places; see how
Sequence of numbers at odd places:
1, 5, 9, 13
Every next number is more by 4 than its previous
Sequence of numbers at even places:
3, 1, -3, ?
We see here that every next number is decreasing by consecutive multiple of 2.
Hence the required number = -3 – 6 = -9 (answer)

Subtract number comprising first 3 digits from the number itself to get the next number
3917 – 391 = 3526
3526 – 352 = 3174 (option ‘4’)
Let’s check it for the next number
3174 – 317 = 2857

If seen closely every number is reverse of a square of a consecutive natural starting from 4; see how
4^2 = 16; reverse of this is 61
5^2 = 25; reverse of this is 52
6^2 = 36; reverse of this is 63
7^2 = 49; reverse of this is 94
8^2 = 64; reverse of this is 46
Therefore the required number
Reverse of 9^2 = 81 i.e, 18 (option ‘2’)

2^1 + 0 = 2
2^2 + 1 = 5
2^3 + 2 = 10
2^4 + 3 = 19
2^5 + 4 = 36
Therefore the next number is
2^6 + 5 = 69

MAHA GUPTA
25*25 – 25 = 600
35*35 – 35 = 1190
Therefore the required number is 45*45 – 45 = 1980

MAHA GUPTA
SAUCER (option ‘2’). The relation between PAPER and PENCIL is that both are items of stationery; likewise the relation between CUP and SAUCER is that both are items of pottery. DRINK is not possible as CUP is a means of drinking of something. CHINA CLAY is not possible as a cup may be made of it. TEA again is not possible as it’s a content that a cup may have inside.

Multiply the number in the first row with its predecessor to get the number in the second row; see how:
3*2 = 6
8*7 = 56
10*9 = 90
2*1 = 2
5*4 = 20
1*0 = 0
Therefore 5 (option ‘3’) is the answer
OR; Square the number in the first row and subtract the number itself from it to get the number in the second row; see how:
3^2 – 3 = 6
8^2 – 8 = 56
10^2 – 10 = 90
2^2 – 2 = 2
5^2 – 5 = 20
1^2 – 1 = 0
Therefore 5 (option ‘3’) is the answer.
