In a certain code language, 'CLOUD' is written as 'DMUAE' and 'WHITE' is written as ‘XIOUI’. How will 'WATER' be written in that language?

XEUIS

So,

( Consonants = +1 and Vowels = next Vowels )

C +1  D

L +1  M

O +1  P

U +1  V

D +1  E

And,

W +1 X

H +1  I

I +1  O

T +1  U

E +1  I

Similarly,

W +1  X

A +1  E

T +1  U

E +1  I

R +1  S

Thus, WATER is coded as XEUIS
