Question : Directions: In each of the following questions, select the one that is different from the other three alternatives.
Option 1: 120 – 560
Option 2: 91 – 299
Option 3: 78 – 169
Option 4: 104 – 429
Correct Answer: 120 – 560
Solution :
Let's check each option –
First option:
120 – 560→120 ÷ 13 = 9.23; 560 ÷ 13 = 43.07 (Both are not the multiples of 13.)
Second option:
91 – 299→91 ÷ 13 = 7; 299 ÷ 13 = 23 (Both are multiples of 13.)
Third option:
78 – 169→78 ÷ 13 = 6; 169 ÷ 13 = 13 (Both are multiples of 13.)
Fourth option:
104 – 429→104 ÷ 13 = 8; 429 ÷ 13 = 33 (Both are multiples of 13.)
So, the first option is different from the other three options as the numbers are not multiples of 13. Hence, the first option is correct.
