Delhi Police Constable Exam Model Paper 8

Consider the English alphabet series to gauge the numerical value of letters.
The pattern followed here is:
$\mathit{O}+\mathit{F}+\mathit{F}+\mathit{I}+\mathit{C}+\mathit{E}=15+6+6+9+3+5=44$
Same pattern will be followed for DESIGN
$.\mathit{D}+\mathit{E}+\mathit{S}+\mathit{I}+\mathit{G}+\mathit{N}=4+5+19+9+7+14=58$
Hence, DESIGN will be coded as 58.
