Question 29

Select the option in which the numbers are related in the same way as are the numbers of the following set.

(26, 63, 124)

Solution

$$26=27-1=3^3-1$$

$$63=64-1=4^3-1$$

$$124=125-1=5^3-1$$

All the numbers are in the form of $$n^3-1$$

Similarly,

$$63=64-1=4^3-1$$

$$124=125-1=5^3-1$$

$$215=216-1=6^3-1$$

$$\therefore\ $$(63, 124, 215) are related in the same way (26, 63, 124) related

Hence, the correct answer is Option A
