In a certain language 'WEAK' is coded as `'4$9beta','REST'` is coded as `'7$8#'` and 'WREK' is coded as `4$beta7`. How will 'KEWRA' be coded in the same code?

Options

A. `7 4 $ beta #`
B. `beta 7 $ 8 #`
C. `# beta 9 7 4`
D. `$ beta 7 9 4`

Answer

D

Explanation

`{:(W,E,A,K,R,E,S,T),(darr,darr,darr,darr,darr,darr,darr,darr),(4,"$",9,beta,7,"$",8,"#"):}`
`{:(W,R,E,K),(darr,darr,darr,darr),(4,7, "$",beta):} rArr 4 "$"beta7`
therefore,
`{:(K,E,W,R,A,),(darr,darr,darr,darr,darr,),(beta,"$",4,7,9,rArr "$"beta794):}`
