SSC CGL 2022 PYQ — Question 56

The correct answer is option 4 i.e. 0

Given:

x + y = 36

Concept used:

If (a + b) = 0 then a³ + b³ = 0

Calculation:

x + y = 36

x - 27 = 9 - y

⇒ (x - 27) + (y - 9) = 0

{(x - 27) + (y - 9)}³ = 0³ (Taking cube on both sides)

⇒ (x - 27)³ + (y - 9)³ = 0 (According to the concept)

So, the required value is 0.
