Answer ⤵⤵⤵⤵⤵⤵⤵
Value = Rs 38640
Step-by-step explanation:
Given:
Cost of scooter is Rs 42000.
Value of scooter depreciated by 8% per annum.
To Find:
What will be the value after one year ?
Solution: 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.
\implies{\rm }⟹ A = 42000(1 – 8/100)¹
\implies{\rm }⟹ A = 42000(100 – 8/100)
\implies{\rm }⟹ A = 42000(92/100)
\implies{\rm }⟹ A = 420 × 92
\implies{\rm }⟹ 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.
∴ 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.
