In each of the following questions, a word is transformed into another word by applying a specific alphabetical pattern to each of its letters. Identify the logic used in the first pair and apply the same logic to the second word to determine the correct answer.
FROST : ITQSR :: CHALK: ?
Show answer & explanation
Correct answer: C
Explanation
First pair:
FROST → ITQSR
F(6)→I(9) = +3
R(18)→T(20) = +2
O(15)→Q(17) = +2
S(19)→S(19) = 0
T(20)→R(18) = −2
Pattern = +3, +2, +2, 0, −2
Now apply to CHALK:
C(3) +3 = F(6)
H(8) +2 = J(10)
A(1) +2 = C(3)
L(12) +0 = L(12)
K(11) −2 =I(9)
Hence, the correct answer is option 3.
