In a certain language 'WEAK' is coded as '4$9$$\beta$$' and 'REST' is coded as '7$8#' and 'WREK' is coded as '4$ $$\beta$$7' .How will 'KEWRA' be coded in the same code ?
By comparing the coding of WEAK, REST and WREK, we can conclude that,
E=$, WK=4$$\beta$$, A=9, R 7,
Hence WREAK coding will contain $,9,7,4,$$\beta$$
Therefore, option D is correct answer.
