In a certain code language, ‘Grains contain wheat rice’ is coded as ‘8 6 # %’, and ‘Rice are hard grains’ is coded as ‘# pr % lm’. What is the code for ‘grains rice’ in that code language?

# %

Given; In a certain code language, ‘Grains contain wheat rice’ is coded as ‘8 6 # %’, and ‘Rice are hard grains’ is coded as ‘# pr % lm’. 

So,

Grains  contain  wheat  rice  =  8  6  #  %

Rice  are  hard  grains  =  #  pr  %  lm

Thus,

Code for either Rice or Grains is # or %

Thus, # % is correct
