In a certain code language, ‘Trucks are heavy and good’ is coded as ‘6 8 7 2 @’, ‘Weight lifts human heavy’ is coded as ‘# % 4 8’, and ‘good are multiples’ is coded as ‘@ pr 6’. What is can be the code for ‘heavy good’ in that language?

8 6

Given; In a certain code language, ‘Trucks are heavy and good’ is coded as ‘6 8 7 2 @’, ‘Weight lifts human heavy’ is coded as ‘# % 4 8’, and ‘good are multiples’ is coded as ‘@ pr 6’. 

So,

TRUCKS  ARE  HEAVY  AND  GOOD  =  6  8  7  2  @

WEIGHT  LIFTS  HUMAN  HEAVY  =  #  %  4  8

GOOD  ARE  MULTIPLES  =  @  pr  6

Thus,

Code for heavy is 8, are is either 6 or @ and for good is either 6 or @ 

But, 8  @ is not given in the options

Therefore, 8 6 is correct.
