Question

3. A new computer costs Rs 100000. The depredation of computers is very high as new models with better technological advantages are coming into the market. The depredation is as high as 50% every year. How much will the cost of computer be after two years?​

Answer 1

Answer:

• The cost of computer after two years will be Rs.$200000$

Step-by-step explanation:

Given : The cost of computer = Rs. $100000$

          The depredation per year = $50$%

To find : The cost of computer after two years =?

Solution :

• It is given that the cost of computer = Rs. $100000$
• The depredation per year is $50$% of cost of the computer.
• ∴ Depredation value per year = $\frac{50}{100} * 100000$

                                          = $50*1000$

                                          = $50000$ Rs.

• Now, depredation value for two years = Rs. $( 2*50000)$

                                                       = Rs. $100000$

• ∴ Cost of computer after two years = Present cost of computer + Depredation value after two years

                                                   = $100000 + 100000$

                                                   = Rs. $200000$  

• ∴ The cost of computer after two years will be Rs. $200000$.

Answer 2

Given,

A new computer cost $100000$ rupees.

The depredation of computer is very high as new models with better technological advantages are coming into market.

The depredation is as high as $50$% every year.

We have to find the cost of computer after two years

Depredation value per year $= 50$%$\times100000$

$= \frac{50}{100}\times100000$

$=50000$

Depredation value per two years =$2\times$Depredation value per year

$= 2\times\frac{50}{100}\times100000$

$= 100000$

Total cost of computer be after two years $= 100000+100000$

$= 200000$

Therefore, the cost of computer be after two years $200000$.
