21. Select the option that will fill in the blank and complete the given series. [RRB NTPC 29/12/2020 (Morning)]

ABCD, ACEG, ______, AEIM

Correct Answer: (a) ADGJ
Solution:

In the first term, difference between the letters = 1.
In the second term, difference between the letters = 2.
And the difference between the letters in fourth term = 4.
We can see the pattern is increasing by 1.
So, the different between the letters in 3rd term = 3
Required term = ADGJ

22. In a certain code language, ‘get up and go’ is written as ‘fa ka la ju’, ‘jump up and dance’ is written as ‘lu la hu fa’, ‘go there jump here’ is written as ‘na lu fa ka’ and ‘and there you come’ is written as ‘na lu ya la'. [RRB NTPC 29/12/2020 (Morning)]

How will ' get up to go there'  be written as in that language?

Correct Answer: (a) fa ju ka na
Solution:From Code (i), Code for “get up go” = fa ka ju
and from Code (iii) and Code (iv), Code for “there” = na
So, code for “get up go there” = fa ju ka na.

23. In certain code language, LEADER is written as ELDARE. [RRB NTPC 29/12/2020 (Evening)]

How will FOUNTAIN be written as in that code language?

Correct Answer: (a) OFNUATNI
Solution:

24. In a certain code language, FIVE is coded as 5137 and RAT is coded as 924. [RRB NTPC 29/12/2020 (Evening)]

How will FEAR be coded as in that code language?

Solution:

26. In a certain code language, PENINSULA is written as 111. [RRB NTPC 30/12/2020 (Morning)]

How will DICHOTOMY be written as in that language?

Correct Answer: (b) 112
Solution:

If we add the place values of the alphabets in PENINSULA we will get 111. Similarly, adding the place values of the alphabets in DICHOTOMY, we get 112.

27. In a certain code, P is coded as 17 and TMR is coded as 54. [RRB NTPC 30/12/2020 (Evening)]

How will NARESH be written in that code?

Correct Answer: (c) 71
Solution:

P is coded as 17
⇒ (place value of P +1) = 16 + 1 = 17
TMR is coded as 54 ⇒ (place values of T, M, R + 3) = 20 + 13 + 18 + 3 = 54
So, NARESH be written in that code as = place values of N, A, R, E, S, H + 6
= 14 + 1 + 18 + 5 + 19 + 8 + 6 = 71

28. In a certain code, LITTLE is coded as 24, PARIS is coded as 23, BOX is coded as 12, and PIN is coded as 12. [RRB NTPC 30/12/2020 (Evening)]

How will DONE be written as in that order?

Correct Answer: (a) 22
Solution:

Here we can see in case of LITTLE number of alphabets = 6, now its code
= 24 ⇒ 2 + 4 = 6
In case of PARIS, number of alphabets = 5, now its code = 23 ⇒ 2 + 3 = 5
In case of both BOX & PIN, number of alphabets = 3, now its code = 12 ⇒ 1 + 2 = 3
So, in case of DONE, number of alphabets = 4, now its code will be 4
= 2 + 2 = 22

29. In a symbolic language, ‘surat is a hot place’ is written as ‘a hot is place surat’ and ‘water vapour to air here’ as ‘to air vapour here water’, then in the same language, ‘shimla is a hill place’ would be written as? [RRB NTPC 04/01/2021 (Morning)]
