The logic is:

Starting from 3 in the clockwise direction:

3 × 2 - 1 = 5

5 × 2 - 2 = 8 

8 × 2 - 3 = 13

13 × 2 - 4 = 22

Similarly, 

22 × 2 - 5 = 44 - 5 = 39

Hence, 39 is the correct answer. 

Given code language:

'nee muk pic' means 'grave and concern';
'ill dic so' means 'every body else'; and
'tur muk so' means 'body and soul'.

So we can decode the following words:

muk - and

so' - body

'tur - soul

Proceeding ahead accordingly, the code for 'every' is either 'ill' or 'dic' and the code for 'concern' is either 'nee' or 'pic'.

The correct answer is Dot Matrix.

Important Points

  • The three most common forms of impact printers are:
    • Dot-matrix.
    • Daisy-wheel.
    • Line printers.

Key Points

• Dot-matrix Printers 
  • The technology behind dot-matrix printing is in such a way that the paper is pressed against a drum (a rubber-coated cylinder).
  • The electromagnetically-driven printhead moves across the paper and strikes the printer ribbon situated between the paper and printhead pin.
  • The impact of the printhead against the printer ribbon imprints ink dots on the paper which create human-readable characters.
