Question 1 :
Given data : 781113 : 168 : : 346923 : ?
To find : The value to be placed in the question mark.
Solution :
If we observe the first half, 781113 : 168 carefully, we can gind that the product of individual digits in the number gives the value 168. As in :
Take 781113 as 7 x 8 x 1 x 1 x 1 x 3
= 56 x 3
= 168 which is the paired number
So, we find the reason behind 781113 : 168 pairing.
Now, apply the same on the number 346923.
346923 should be written as 3 x 4 x 6 x 9 x 2 x 3
= 12 x 54 x 6
= 72 x 54
= 3888
So, the pair is 346923 : 3888
Therefore, 781113 : 168 : : 346923 : 3888 (Option B)
Question 2:
Given data : DE : 02 : : BR : ?
To find : The value to be placed in the question mark.
Solution :
The logic applied here is the product of the corresponding numbers of the letters present in the string, while we start numbering from A to Z as 1 to 26, and then reverse the resultant.
A=01, B=02, C=03, D=04, E=05,
F=06, G=07, H=08, I=09, J=10,
K=11, L=12, M=13, N=14, O=15,
P=16, Q=17, R=18, S=19, T=20,
U=21, V=22, W=23, X=24, Y=25,
Z=26
As in :
From DE, D = 4, E = 4.
D x E = 4 x 5 = 20
Reverse value of 20 is 02.
That's how we got the pair DE : 20
If DE : 02, then BR : ?
From BR, B = 2 , R = 18.
B x R = 2 x 18 = 36
Reverse value of 36 is 63, which is the pair value of BR.
Therefore, DE : 02 : : BR : 63 (Option A)
