Question 7

In the following question, select the related number pair from the given
alternatives.
19 : 363 :: ? : ?

Solution

The logic here is

$$363=19^2+2$$ $$\longrightarrow\ $$ $$\text{second number}=\text{first number}^2+2$$

Similarly,

$$171=13^2+2$$ $$\longrightarrow\ $$ $$\text{second number}=\text{first number}^2+2$$

$$\therefore\ $$13 : 171 are related in the same way 19 : 363 are related.

Hence, the correct answer is Option B
