Answer: The value after one year will be Rs 38640
Step-by-step explanation:
Value = Rs 38640
Step-by-step explanation:
Given:
Cost of scooter is Rs 42000.
Value of scooter depreciated by 8% per annum:
We have to find the value after one year,
Here we have,
Principal = Rs 42000
Rate = 8% per annum.
Time = 1 year
Using formula
Amount = Principal (1 – Rate/100)ⁿ
(–) because the value decreasing.
A = 42000(1 – 8/100)¹
A = 42000(100 – 8/100)
A = 42000(92/100)
A = 420 × 92
A = 38640
Hence, the value after one year will be Rs 38640.
[ Another method ]
C.P is Rs 42000.
Value is decreasing by 8% per year.
Therefore, Value of scooter after 1 year will be
42000 – 8% of 42000
42000 – (8/100 × 42000)
42000 – (8 × 420)
42000 – 3360
38640
Hence, the value after one year will be Rs 38640
