Explanation
Value after 5 years $$=15025\times(1-(\dfrac{20}{100})^5)$$
$$=15025\times\>0.32768=Rs.4923.39$$
Given that
Original value of the scooter $$=Rs.14000$$
Rate of depreciation $$=2$$%
The value of the scooter after $$4$$ years
$$ =14000\times {{\left( 1-\dfrac{2}{100} \right)}^{4}} $$
$$ =14000\times {{\left( 0.98 \right)}^{4}} $$
$$ =14000\times 0.92236816 $$
$$ =12913.154 $$
Thus, the value of the scooter after $$4$$ years $$=Rs\,\,12913.154$$
Hence, this is the answer.
