Answer 2

A motor bike costs Rs 75000. If it depreciates at the rate of 10% per annum, what is the value of the bike after 3 years.

Answer :

• Cost of motor bike is Rs 75000

• It depreciates at the rate of 10% per year .

• value of it after 3 years .

In first year it will depreciate =

$\longrightarrow\bf{ \dfrac{10}{100}\times 75000}$

$\longrightarrow\bf{ 10\times 750}$

$\longrightarrow\bf{ 7500}$

Its value after 1 year =

$\longrightarrow\bf{ 75000 - 7500}$

$\longrightarrow\bf{ 67500}$

• Therefore its price after 1 year is Rs 67500

In second year it will depreciate =

$\longrightarrow\bf{ \dfrac{10}{100}\times 67500}$

$\longrightarrow\bf{ 10\times 675}$

$\longrightarrow\bf{ 6750}$

Its value after 2 years =

$\longrightarrow\bf{ 67500 - 6750}$

$\longrightarrow\bf{60750}$

In third year it will depreciate =

$\longrightarrow\bf{ \dfrac{10}{100}\times 60750}$

$\longrightarrow\bf{ \dfrac{10}{10}\times 6075}$

$\longrightarrow\bf{ 6075}$

its value after 3 year =

$\longrightarrow\bf{60750 - 6075}$

$\longrightarrow\bf{54675}$

• Therefore its value after 3 year is rs 54675
