Option 1: 23 : 153
Option 2: 15 : 97
Option 3: 16 : 106
Option 4: 26 : 174
Correct Answer: 16 : 106
Solution :
Let's check the given options –
First option:
23 : 153; 23 × 7 = 161; 161 – 8 = 153
Second option:
15 : 97; 15 × 7 = 105; 105 – 8 = 97
Third option:
16 : 106; 16 × 7 = 112; 112 – 8 = 104 ≠ 106
Fourth option:
26 : 174; 26 × 7 = 182; 182 – 8 = 174
So, the third option is different from the other three options. Hence, the third option is correct.
