Text Solution

What is known?

Original Value, Rate of Depreciation

What is unknown?

The value of scooter after \(1\) year

Reasoning:

Original value of the scooter \(= \rm{Rs}\, 42,000\)

Rate of depreciation \(= 8\%\)

Steps:

The value of the scooter after \(1\) year

\[\begin{align} &= 42000 - \left( {42000 \times \frac{8}{{100}}} \right) \\ &= 42000 - \left( {42000 \times \frac{2}{{25}}} \right) \\ &= 42000 - \left( {1680 \times 2} \right) \\ &= 42000 - 3360 \\ &= 38640 \\ \end{align}\]

The value of the scooter after \(1\) year (\(8\%\) depreciation rate) \(= \rm{Rs}\, 38640.\)
