In a certain code language, ‘Phones are burning’ is coded as ‘7 8 3’, and ‘That coach was burning’ is coded as ‘6 3 2 4’. What can be the code for ‘are’ in that language?

8

Given; In a certain code language, ‘Phones are burning’ is coded as ‘7 8 3’, and ‘That coach was burning’ is coded as ‘6 3 2 4’. 

As per our observations,

--> Code for burning is 3 because it is common on both strings thus, 01 is not answer.

--> And, option 2 and 4 is eliminated because these codes are related to 2nd string

--> Only option 3 is possible, because 3 or 7 is code for 'are' but as per the optons we have 8 

Thus, the code for are is 8
