Option 1: 20
Option 2: 2
Option 3: 10

Option 1: 40
Option 2: 39

Option 1: Was wild with excitement
Option 2: Was dizzy

Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given sets. (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 /subtracting /multiplying etc. 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (16, 22, 28) (14, 19, 23)
Option 1: (12, 18, 25)
Option 2: (13, 21, 27)
Option 3: (15, 26, 31)
Option 4: (17, 24, 41)
Correct Answer: (15, 26, 31)
Solution : Given: (16, 22, 28); (14, 19, 23)
The pattern here is – (The third number – The first number) + 10 = The second number (16, 22, 28)→(28 – 16) + 10 = 12 + 10 = 22 (14, 19, 23)→(23 – 14) + 10 = 9 + 10 = 19 Let's check the options – First option: (12, 18, 25)→(25 – 12) + 10 = 13 + 10 = 23 ≠ 18 Second option: (13, 21, 27)→(27 – 13) + 10 = 14 + 10 = 24 ≠ 21 Third option: (15, 26, 31)→(31 – 15) + 10 = 16 + 10 = 26 Fourth option: (17, 24, 41)→(41 – 17) + 10 = 24 + 10 = 34 ≠ 24
So, only the third option follows the pattern as followed by the given set of numbers. Hence, the third option is correct.
