Correct Answer: 150
Solution : Given: 20 : 30 :: 100 : ?
Multiply the first number by 1.5, to get the second number in each number pair – Like, 20 : 30→20 × 1.5 = 30 Similarly, follow the same pattern for 100 : ?→100 × 1.5 = 150
So, 150 is the required missing number. Hence the third option is correct.
