Option 1: 36 – 145
Option 2: 16 – 63
Option 3: 91 – 363
Option 4: 64 – 255
Correct Answer: 36 – 145
Solution :
Let's check the options –
First option:
36 – 145; 36 x 4 = 144 – 1 = 143
≠
145
Second option:
16 – 63; 16 x 4 = 64 – 1 = 63
Third option:
91 – 363; 91 x 4 = 364 – 1 = 363
Fourth option:
64 – 255; 64 x 4 = 256 – 1 = 255
So, in the first option, the second number is not equal to one less than the fourth multiple of the first number. Hence, the first option is correct.
