​In a certain code language, 'FAST' is written as '7-39', and 'LINE' is written as '21-19'. Which of the following are correct matches as per the given code language? ​

WORD	CODE
(i) DOME	(W) 15-27
(ii) FISH	(X) 18-15
(iii) COMB	(Y) 19-18

​​Given:

'FAST' → '7-39'

'LINE' → '21-19'

Logic: ​

First number = sum of first two letters

Second number = sum of last two letters

F + A = 6 + 1 = 7 

S + T = 19 + 20 = 39

L + I = 12 + 9 = 21

N + E = 14 + 5 = 19

(i) DOME

​D + O = 4 + 15 = 19​

​M + E = 13 + 5 = 18

Thus, DOME matches with Y (19-18)

​F + I = 6 + 9 =15

​S + H = 19 + 8 = 27​

Thus, FISH matches with W (15-27) 

​C + O = 3 + 15 = 18

M + B = 13 + 2 = 15

COMB → 18-15

Thus, COMB matches with X (18-15)

So,  i-Y, ii-W, iii-X only follow.

Thus, the correct option is: (c)
