In a cestain code language, ‘QUILT’ is written as ‘RXJOU’ and ‘BLEAK’ is written as ‘COFDL’. How will ‘CHAIR’ be written in that language?

Correct option is A

Given - ‘QUILT’ is written as ‘RXJOU’ and ‘BLEAK’ is written as ‘COFDL’. How will ‘CHAIR’ be written in that language?

Logic - addition of  , +1, +3, +1, +3, +1 in place values of given letters within the word

Place values of letters 

first relation
QUILT’ is written as ‘RXJOU’
Q + 1 = R,
U + 3 = X
I + 1 = J
L + 3 = O
T + 1 = U
Second pair
‘BLEAK’ is written as ‘COFDL
B + 1 = C
L + 3 = O
E + 1 = F
A + 3 = D
K + 1 = L
Similarly, CHAIR
C + 1 = D
H + 3= K
A + 1 = B
I + 3 = L
R + 1= S
So DKBLS is the correct answer.
