Select the option that is related to the fifth letter-number cluster in the same way as the second letter-number cluster is related to the first letter-number cluster and fourth letter-number cluster is related to third letter-number cluster.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 – Operations on 13 such as adding / subtracting / multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
JT310 : WM218 :: AT520 : WD428 :: LD620 : ?
Show answer & explanation
Correct answer: C
Explanation
Just as
JT310:WM218
J(10) + W(23) = 33
T(20) + M(13) = 33
310 - 218 = 92
And
AT520:WD428
A(1) + W(23) = 24
T(20) + D(4) = 24
520 - 428 = 92
Similarly,
LD620: ?
620 - 92 = 528
L(12) + G(7) = 19
D(4) + O(15) = 19
