Correct Answer: 21 – 40
Solution :
Let's check each option
–
First option:
19 – 38; 19 × 2 = 38
Second option:
21 – 40; 21 × 2 = 42 ≠ 40
Third option:
23 – 46; 23 × 2 = 46
Fourth option:
16 – 32; 16 × 2 = 32
So, the second option is different from the other three options as twice the first number is 42 instead of 40. Hence, the second option is correct.
