Correct Answer: 12 – 167
Solution :
Let's check the options –
First option:
7 – 71; (7 × 10) + 1 = 70 + 1 = 71
Second option:
11 – 111; (11 × 10) + 1 = 110 + 1 = 111
Third option:
8 – 81; (8 × 10) + 1 = 80 + 1 = 81
Fourth option:
12 – 167; (12 × 10) + 1 = 120 + 1 = 121 ≠ 167
After adding 1 to the product of the first number and 10, only the fourth option yields 121 instead of 167. Hence, the fourth option is correct.
