Question : Directions: Select the option related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.
5 : 50 :: 17 : 170 :: 19 : ?
Option 1: 190
Option 2: 180
Option 3: 200
Option 4: 210
Correct Answer: 190
Solution :
Given:
5 : 50 :: 17 : 170 :: 19 : ?
Multiply the first number by 10, to get the second number in each number pair –
Like, 5 : 50→5 × 10 = 50
And, 17 : 170→17 × 10 = 170
Similarly, follow the same pattern for 19 : ?→
19 × 10 = 190
So, 190 is the required answer. Hence, the first option is correct.
