11. In certain code language, TRUNK is coded as VXVPL. How will GLOBE be coded in that language ? [RRB NTPC 19/01/2021 (Evening)]

Correct Answer: (a) LPRDF
Solution:

TRUNK is coded as YVXPL
T + 5 = Y
R + 4 = V , U + 3 = X
N + 2 = P , K +1 = L
Similarly,
GLOBE be coded LPRDF

12. In a certain code language, COLOUR is written as 51714172320. Which word will be written as 61714141720 in that code ? [RRB NTPC 19/01/2021 (Evening)]

Correct Answer: (a) DOLLOR
Solution:

COLOUR = 51714172320
C = 3 + 2 = 5
O = 15 = 15 + 2 = 17
L = 12 = 12 + 2 = 14
O = 15 = 15 + 2 = 17
U = 21 = 21 + 2 = 23
R = 18 = 18 + 2 = 20
Similarly,
61714141720 = DOLLOR

13. Given below are few statements and their respective codes in a particular language. [RRB NTPC 20/01/2021 (Morning)]

Horse are Cat - XYT
Cat is Blue - TMZ
Blue is Cloud - ZMS
Which of the given options will be the code for the following statement in that language.
Blue Cat is Cloud - ?

Correct Answer: (d) ZTMS
Solution:

Comparing line 1 and line 2 we get the code for Cat = T;
And from the line 3, we get the codes for Blue is Cloud - ZMS;
So, the code for ‘Blue Cat is Cloud’ will be - ZTMS.

14. If CPHUDQ = 6 and BOY = 6, then which of the given options will FUNDAMENTAL be equal to? [RRB NTPC 20/01/2021 (Morning)]

Correct Answer: (d) 3
Solution:

The sum of the place values of CPHUDQ = 69 = 6 + 9 = 15 = 1 + 5 = 6
The sum of the place values of BOY = 42 = 6
Then the sum of the place values of FUNDAMENTAL = 111 = 3

15. If J is coded as N, R is coded as V and X is coded as B, then how will you code JOY ? [RRB NTPC 20/01/2021 (Evening)]

Correct Answer: (c) NSC
Solution:

Alphabet + 4
J + 4 = N, O + 4 = S, Y + 4 = C
Code for JOY = NSC
