In a certain code language, 'WENT' is coded as '2769', 'CORN' is coded as '8941', 'TIRE' is coded as '4652', 'OATS' is coded as '2380'. What is the code for 'OAI' in that code language ?

835

Given; In a certain code language, 'WENT' is coded as '2769', 'CORN' is coded as '8941', 'TIRE' is coded as '4652', 'OATS' is coded as '2380'. 

So,

W  E  N  T  =  2  7  6  9

C  O  R  N  =  8  9  4  1

T  I  R  E  =  4  6  5  2

O  A  T  S  =  2  3  8  0

Thus,

Code for T is 2, E is 6, R s 4, N is 9, W is 7, C is 1, O is  8, I is 5

And,

either A or O is coded as 3 or 0

Thus, code for OIA is 835.
