Solution

Let the present value of scooter = P

And value of scooter after 1 year = A

Present value of given scooter (P) = Rs 42,000

Time (n) = 1 year

Rate of depreciation (R) = 8% p.a.

Total cost of scooter after 1 year

(A) = P `(1 + R/100)^n`

= 42000 `(1 + 8/100)^1`

= 3360 

= 42000 – 3360 

= ₹38,640

अतः, 1 वर्ष के बाद स्कूटर का मूल्य(A) = 38,640 रु.
