Question : Directions: Four triads of numbers have been given out of which three are alike in some manner and one is different. Select a different one.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Option 1: 25 – 45 – 65
Option 2: 8 – 28 – 48
Option 3: 38 – 58 – 78
Option 4: 17 – 27 – 67

Correct Answer: 17 – 27 – 67
Solution : Let's check the options –
First option:
25 – 45 – 65; 25 + 20 = 45 and 45 + 20 = 65
Second option:
8 – 28 – 48; 8 + 20 = 28 and 28 + 20 = 48
Third option:
38 – 58 – 78; 38 + 20 = 58 and 58 + 20 = 78
Fourth option:
17 – 27 – 67; 17 + 10 = 27 and 27 + 40 = 67
So, only the fourth option is different from the others as the difference between the numbers is 10, 40 instead of 20, 20. Hence, the fourth option is correct.
