23. In certain code language. PETAL is coded as 11-22- 7-26-15. How will UNDER be coded in that language? [RRB NTPC 07/04/2021 (Evening)]

Correct Answer: (c) 6-13-23-22-9
Solution:

Place value of opposite letters.
∴ UNDER = FMWVI (6 -13 - 23 - 22 - 9)

24. Which of the following codes is used to write the word ENQUIRY as FLTQNLF? [RRB NTPC 08/04/2021 (Morning)]

The word RESERVATION has been
coded using 4 different codes.
Code 1 : SGVIWBBHRYY
Code 2 : SCVAVPHLREY
Code 3 : TGUGTXCVKQP
Code 4 : PCCQPTYRGML

Correct Answer: (a) Code 2
Solution:

From the given codes we can
observe that in code 2
Code for R = R + 1 = S
Code for E = E - 2 = C
Code for S = S + 3 = V and so on
And code for ENQUIRY = FLTQNLF is
coded according to code 2.

25. Which of the following codes is used to write the word STATION as RUZUHPM? [RRB NTPC 08/04/2021 (Morning)]

The word LOCOMOTIVE has been
coded using 4 different codes.

Code 3 : KPBPLPSJUF
Code 4 : MQFSRUAQEO

Correct Answer: (b) Code 3
Solution:

In LOCOMOTIVE , According to given
code 3, the code of
LOCOMOTIVE =
KPBPLPSJU(+1 , -1 , +1 , -1 , +1 , -1 , so on)
and in code of STATION , the code of
RUZUHPM is same

26. In a certain code language, BRAIN is written as AQZHM. How will BEAN be written as in that code language? [RRB NTPC 08/04/2021 (Morning)]

Correct Answer: (d) KMHJDF
Solution:

P is middle number , between O and Q .
U is middle number , between T and V .
N is middle number , between M and O
Similarly ,LIE is written as KMHJDF

28. In a code language, AROMA is written as ‘@%U@S’, ELE is written as ‘DD#’ and ROSE is written as ‘%$D^’. How will MAREO be written as in that language? [RRB NTPC 08/04/2021 (Evening)]

Correct Answer: (a) @U%$D
Solution:

AROMA - @%U@$ ----(i)
ELE - DD# ------(ii)
ROSE - %$D^ -----(iii)
RO common on equ. (i)&(iii)
E is common on equ. (ii)&(iii)
So that MAREO is written as @U%$D

29. FILE is written as DKJG in a certain code language. How will RAIL be written as in that language? [RRB NTPC 23/07/2021 (Morning)]

Correct Answer: (d) PCGN
Solution:

F - 2 = D , I + 2 = K, L - 2 = J, E + 2 = G
Similarly,
R - 2 = P, A + 2 =C, I - 2 = G, L + 2 =N
RAIL = PCGN
