SSC CGL 2022 PYQ — Question 75

The correct answer is option 1 i.e. -281250

Formula used:

x³ + y³ + z³ = 3xyz              ---- (1)

when x + y + z = 0

Calculations:

Using equation (1), we get

⇒ 25 - 75 + 50 = 0

Hence, x = 25, y = -75 and z = 50

⇒ 25³ - 75³ + 50³ = 3 × 25 × (-75) × 50

⇒ - 281250
