In a certain code language, ‘mould soft gel’ is written as ‘8 6 4’, ‘gel is not hard’ is written as ‘pr kc 8 3’ and ‘hard is grey mould’ is written as ‘kc 3 4 9’. How will ‘grey soft’ be written in that language?

9 6

Given; In a certain code language, ‘mould soft gel’ is written as ‘8 6 4’, ‘gel is not hard’ is written as ‘pr kc 8 3’ and ‘hard is grey mould’ is written as ‘kc 3 4 9’

So,

mould  soft  gel  =  8   6   4

gel  is  not  hard  =  pr  kc  8  3

hard  is  grey  mould  =  kc  3  4  9

Thus,

grey is coded as 9, soft is 6

Therefore,

grey soft will be coded as 9 6
