A scooty was bought at rs 42000.its value depreciated at the rate of 8% per annum. Find the value after one year

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.
