Correct Answer: 7 – 19
Solution :
Let's check the options –
First option:
14 – 39→14 × 3 = 42; 42 – 3 = 39
Second option:
11 – 30→11 × 3 = 33; 33 – 3 = 30
Third option:
7 – 19→7 × 3 = 21; 21 – 3 = 18 ≠ 19
Fourth option:
17 – 48→17 × 3 = 51; 51 – 3 = 48
So, only the third option is different from the other three options as here, the resultant is 18 instead of 19. Hence, the third option is correct.
