Question
Evaluate \(20^3 + (-16)^3 + (-4)^3\)
This question was previously asked in
RRB NTPC 2025 Under Graduate CBT 1 Question Paper PDF (20-Jun-2026) (Shift 3)
The correct answer is
3840
Compute each cube: \(20^3=8000,\ (-16)^3=-4096,\ (-4)^3=-64\).
Sum: \(8000-4096-64=3840\).
Hence, the value of the expression is 3840.
