Answer» Cost price of the scooter(c) = Rs16000 Let the Rate of depreciation = d % scooter price after 2 years S = Rs 14440 S = c ×(100 - d )/100× (100-d)/100 14440 = 16000 × (100 - d )^2 /10000 ( 14440 × 10000)/16000 = ( 100 - d )^2 ( 144400/16) = ( 100 - d )^2 9025 = ( 100 - d )^2 95 = 100 - d d = 100 - 95 d = 5 % Rate of the depreciation = d = 5 % |
