Correct Answer: 653
Solution :
Given:
1. MOCK ⇒ 9326
2. MINK ⇒ 2538
3. LUNE ⇒ 5041
4. LOUT ⇒ 6714
By comparing all the three coded words, we find that –
In words 1 and 2 the common letter is
M/K
and the common code is
3/2
.
In words 2 and 3 the common letter is
N
and the common code is
5
.
In words 1 and 4 the common letter is
O
and the common code is
6
.
In words 3 and 4 the common letter is
L/U
and the common code is
4/1
.
The remaining words and codes in word 1 are
C
and
9
; in word 2 are
I
and
8
; in word 3 are
E
and
0
; in word 4 are
T
and
7
.
Finally, M/K⇒3/2; N⇒5; O⇒6; L/U⇒4/1; C⇒9; I⇒8; E⇒0; T⇒7
So, the code for ONM is 653 or 652 but in option, we have only 653.
Therefore, the code for ONM is 653. Hence, the second option is correct.
