AB 112 is related to CD 102. In the same way, EF 145 is related to GH 135. To which of the given options is IJ 189 related, following the same logic?
KL 179
KL 180
MN 179
KL 199
KL 179
Observe the pattern: Letters increment by 2 positions (A to C, B to D) while the number decreases by 10 (112 to 102).
Observe the pattern: Letters increment by 2 positions (A to C, B to D) while the number decreases by 10 (112 to 102).
Analyze Letter Transformation
The letter pattern is constant: A(1), B(2) тЖТ C(3), D(4). This is an increase of +2 for each letter. Similarly, EF(5, 6) тЖТ GH(7, 8) (+2 increase). Following this, IJ(9, 10) must become KL(11, 12).
Analyze Number Transformation
The number pattern follows a consistent subtraction of 10: 112 - 10 = 102, 145 - 10 = 135. Applying this rule to 189: 189 - 10 = 179.
Combine Results
Combining the next letters (KL) and the calculated number (179) gives the result KL 179.
B: Incorrect because the number 180 does not follow the subtract 10 rule. C: Incorrect because the letters MN do not follow the +2 letter advancement rule. D: Incorrect because the number 199 is not 189 - 10.
A is correct because the logic follows a +2 advancement for the letter pair and a -10 subtraction for the numeric value, resulting in KL 179.
In letter-number analogies, always check the letter increment and number difference separately; they rarely share the same rule.
