Question 46

Select the option in which the numbers are related in the same way as are the numbers in the given set.
(15, 556, 331)

Solution

The logic here is

$$556-331=225=15^2$$ $$\longrightarrow\ $$ $$\text{second number}-\text{third number}=\text{first number}^2$$

Similarly,

$$159-78=81=9^2$$ $$\longrightarrow\ $$ $$\text{second number}-\text{third number}=\text{first number}^2$$

$$\therefore\ $$(9, 159, 78) are related in the same way as (15, 556, 331) are related.

Hence, the correct answer is Option A
