Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 15 - 45.
Logic: Second digit of 1st number × 9 = Second number
23 - 27 ⇒ 3 × 9 = 27
Option 1: 15 − 25 ⇒ 5 × 9 = 45 (not equal to 25)
Option 2: 11 − 33 ⇒ 1 × 9 = 9 (not equal to 33)
Option 3: 15 − 45 ⇒ 5 × 9 = 45
Option 4: 11 − 55 ⇒ 1 × 9 = 9 (not equal to 55)
