Question : Directions: Select the option in which the two numbers are related in the same way as the numbers in the given number pair.
40 : 19 :: ? : ?
Option 1: 28 : 13
Option 2: 20 : 11
Option 3: 34 : 17
Option 4: 46 : 23
Correct Answer: 28 : 13
Solution :
Given:
40 : 19 :: ? : ?
Like, 40 : 19→(19 × 2) + 2 = 38 + 2 = 40
Let's check the options –
First Option:
28 : 13→(13 × 2) + 2 = 26 + 2 = 28
Second Option:
20 : 11→(11 × 2) + 2 = 22 + 2 = 24 ≠ 20
Third Option:
34 : 17→(17 × 2) + 2 = 34 + 2 = 36 ≠ 34
Fourth Option:
46 : 23→(23 × 2) + 2 = 46 + 2 = 48 ≠ 23
So, only the number pair in the first option follows the same pattern as the given pair of numbers. Hence, the first option is correct.
