Select the option that is related to the first letter-number cluster in the same way as the fourth letter-number cluster is related to the third letter-number cluster and sixth letter-number cluster is related to fifth 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)
EJ18 : ? :: LT20 : RJ400 :: SK22 : IQ484
Show answer & explanation
Correct answer: B
Explanation
EJ18 : ? :: LT20 : RJ400 :: SK22 : IQ484
The positions of the letters have been altered, and the number has been squared.
LT20 → RJ400
L(12) → R(18) = +6
T(20) → J(10) = -10
20² = 400
SK22 → IQ484
S(19) → I(9) = -10
K(11) → Q(17) = +6
22² = 484
Rule:
First letter → -3
Second letter → -7
Number → Square
Now apply to EJ18:
E(5) → H(8) = +3
J(10) → C(3) = -7
18² = 324
