The value of a machine depreciates by 10% every year. After two years the value of machine decreases by : |
16% 17% 18% 19% |
19% |
The correct answer is Option (4) → 19% Depreciation follows an experimental decay formula, $V=P×(1-r)^t$ $=P×(1-0.10)^2$ $=P×0.81$ Decrease = $P-V$ $=P-P×0.81$ $=P×6.19$ ∴ Machine value decreases by 19% |
