The number 253 - 753 + 503.
Calculation:
253 - 753 + 503
⇒ 15625 - 421875 + 125000
⇒ - 281250
∴ The required answer is - 281250.
Alternate MethodWe know that,
If a + b + c = 0, then a3 + b3 + c3 = 3abc
a = 25, b = -75 and c = 50
a + b + c = 25 -75 +50 = 0
253 - 753 + 503 = 3 × 25 × -75 × 50 = -281250
