Question 46

Select the option in which the numbers are related in the same way as are the numbers of the following set.
(31, 18, 7)

Solution

The logic here is

31 + 18 = 49 = 7$$^2$$ $$\longrightarrow\ $$ first number + second number = third number$$^2$$

Similarly,

90 + 54 = 144 = 12$$^2$$

$$\therefore\ $$(90, 54, 12) are related in the same way as (31, 18, 7) related

Hence, the correct answer is Option A
