Option 1: 20 : 120
Option 2: 37 : 210
Option 3: 42 : 222
Option 4: 49 : 350
Correct Answer: 20 : 120
Solution :
Given:
30 : 130 :: ? : ?
Here, the difference between the numbers of both pairs is 100.
30 : 130→130 – 30 = 100
Let's check the options –
First option:
20 : 120→120 – 20 = 100
Second option:
37 : 210→210 – 37 = 173 ≠ 100
Third option:
42 : 222→222 – 42 = 180 ≠ 100
Fourth option:
49 : 350→350 – 49 = 301 ≠ 100
So, only the first option follows the same pattern as followed by the given pair. Hence, the first option is correct.
