Question:-

The price of a car is 3,25,000. The value of the car depreciates by 20% in the first year and after that it depreciates 25% every year. What will be the car's value after three years.

Required Answer:-

Given:-

  • The price of a car is 3,25,000
  • The value depreciates by 20% in the first year.
  • The value depreciates 25% in second year.
  • The value depreciates 25% in second year.

To Find:-

  • The value of the car after 3 years.

Solution:-

First, let's see what is "Depreciation"

Depreciation refers to when the value of something goes down over time.

The value of a car is usually decreases in value with time. Therefore its value is said to depreciate.

Now, we have to find the value of the car each year respectively.

  • Value depreciation on 1st year is by 20%

Value of the car in 1st year:-

=> 3,25,000 - (20% of 3,25,000)

=> 3,25,000 - (20/100 × 3,25,000)

=> 3,25,000 - 65,000

=> 2,60,000

Hence, the value of the car after 1st year is Rs. 2,60,000

Again,

  • Value depreciation on 2nd year is 25%

Value of the car in 2nd year:-

=> 2,60,000 - (25% of 2,60,000)

=> 2,60,000 - (25/100 × 2,60,000)

=> 2,60,000 - 65,000

=> 1,95,000

Hence, the value of the car after 2nd year is Rs. 1,95,000

Now,

  • Value depreciation on 3rd year is 25%

Value of the car in 3rd year:-

=> 1,95,000 - (25% of 1,95,000)

=> 1,95,000 - (25/100 × 1,95,000)

=> 1,95,000 - 48,750

=> 1,46,250

Hence, the value of the car in 3rd year is Rs. 1,46,250

Therefore, the value of the car after 3 years will be Rs. 1,46,250

\begin{gathered} \begin{gathered} \\ \underline{\underline{\sf{\pmb{Solution:}}}}\\\end{gathered} \end{gathered}Solution:Solution:

Let us assume that , the cost price of the article is x

Now, let's take a careful look at the question. We are told that the article was sold at a gain of 10% . Which means the gain was 10% on the cost price. Again, it would be gain of 25% if it had been sold for 30 more. This means, the difference of the sum of money between the gain of 10% and the gain of 25% is 30.

Let's solve this!

_________________________

\sf{In \: 10\% \: gain, \: the \: cost \: price \: is = \: \bold{x \times 10\% }}In10%gain,thecostpriceis=x×10%

\sf{\rightarrow{In \: 10\% \: gain, \: the \: cost \: price \: is = \: \bold{x \times \dfrac{10}{100} }}}→In10%gain,thecostpriceis=x×10010

\begin{gathered} \begin{gathered} \sf{\rightarrow{In \: 10\% \: gain, \: the \: cost \: price \: is = \: \bold{ \dfrac{10x}{100}} \blue{ - - - - - - - - - - - (1)} }}\\\end{gathered} \end{gathered}→In10%gain,thecostpriceis=10010x−−−−−−−−−−−(1)

Again,

If the gain was 25%,

\sf{In \: 25\% \: gain, \: the \: cost \: price \: is = \: \bold{x \times 25\% }}In25%gain,thecostpriceis=x×25%

\sf{\rightarrow{In \: 25\% \: gain, \: the \: cost \: price \: is = \: \bold{x \times \dfrac{25}{100} }}}→In25%gain,thecostpriceis=x×10025

\begin{gathered} \begin{gathered} \sf{\rightarrow{In \: 25\% \: gain, \: the \: cost \: price \: is = \: \bold{ \dfrac{25x}{100} \blue{ - - - - - - - - - - (2)}}}}\\\end{gathered}\end{gathered}→In25%gain,thecostpriceis=10025x−−−−−−−−−−(2)

From equation 1 and 2 , we can write:-

\bold{\tt{ \dfrac{25x}{100} - \dfrac{10x}{100} = 30}}10025x−10010x=30

\begin{gathered}\begin{gathered}\\\implies{\tt{ \dfrac{25x - 10x}{100} = 30}}\end{gathered}\end{gathered}⟹10025x−10x=30

\begin{gathered} \begin{gathered} \\ \implies{\tt{25x - 10x = 3000}} \: \: \: \: \: \: \boxed{\rm{Multiplying \: both \: sides \: by \: 100}}\end{gathered}\end{gathered}⟹25x−10x=3000Multiplyingbothsidesby100

\begin{gathered} \begin{gathered}\\\implies{\tt{15x = 3000}}\end{gathered} \end{gathered}⟹15x=3000

\begin{gathered} \begin{gathered} \\ \implies{\tt{x = \dfrac{3000}{15} }} \: \: \: \: \: \: \: \boxed{\rm{Dividing \: both \: sides \: by \: 15}}\end{gathered} \end{gathered}
