Question

Ashish purchased a boat for rupees 16000. if after 2 years the price of the boat became 14440. find the rate of depreciation.​

Answer 1

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 %

I hope this helps you.
