3. In a certain code language, GOAL is written as 3671 and HUNT is written as 4985. How will HANG be written as in that language? [RRB NTPC 05/03/2021 (Morning)]

Correct Answer: (b) 4783
Solution:

G = 3, O = 6, A = 7, L = 1
and H = 4, U = 9, N = 8, T = 5
So that HANG is written as
H = 4 , A = 7 , N = 8 and G = 3
HANG = 4783

4. In a certain code language, ‘Ram works there’ is written as ‘huge tyo tre’, ‘Sima Study there’ as ‘noe dow tre’, and ‘Ram study here’ is written as ‘huge dow try’, then how will ‘Ram there’ and ‘Sima work’ be written as in that language respectively? [RRB NTPC 05/03/2021 (Morning)]

Correct Answer: (c) ‘huge tre’ and ‘noe tyo’
Solution:

Ram works there = huge tyo tre ---- (i)
Sima Study there = noe dow tre ------- (ii)
Ram study here = huge dow try -------- (iii)
Ram there’ and ‘Sima work = ?
Now, Ram is common in equation (i) & (iii)
Ram = huge
There is common in equation (i) & (ii)
There = tre
And work = tyo also Sima = noe
Hence , Ram there’ and ‘Sima work =
huge tre and noe tyo

5. In a code language , BIHAR is written as AGEWM and GUJARAT is written as FSGWMUM. How will KASHMIR written as in that language? [RRB NTPC 05/03/2021 (Evening)]

8. In a certain code language, ABLE is written as 3781, HAIR is written as 4365 and TOOL is written as 9008. How will RATTEL be written as in that language? [RRB NTPC 07/03/2021 (Evening)]

Correct Answer: (d) 539918
Solution:

ABLE is written as 3781,
HAIR is written as 4365 and TOOL is
written as 9008.
From the above examples, we can find
code for the required letters.
R → 5, A → 3, T → 9, E → 1, L → 8
Then the code for RATTEL will be
= 539918 ;

9. In a certain code language RATE is written as IZGV, How will FUND be written as in that language . [RRB NTPC 07/03/2021 (Evening)]

Correct Answer: (c) UFMV
Solution:

In a certain code language
RATE is written as IZGV ;
i.e. the code is made by replacing the
letters by their opposite letters ;
[opposite = (27 - place value)]
So, FUND will be written as UFMW in that
language.

10. In a code language, GOOFY is written as EMMDW. How will EMMA be written as in that code language? [RRB NTPC 08/03/2021 (Morning)]

Correct Answer: (b) CKKY
Solution:

In a code language, GOOFY is
written as EMMDW ;
i.e. the code for each letter in the code
(EMMDW) is found by reducing 2 from
each letter of GOOFY.
So, the code for EMMA will be :
E - 2 = C, M - 2 = K, A - 2 = Y ; i.e. ⇒ CKKY ;
