Question

Karan buys a scooty for 40000.The value of scooty depreciates at rate of 10% per annum.Find value after 2 years?

Answer 1

As the rate of decrease in the cost of the scooter is 10% per year. Therefore, for the first year the cost will reduce by 40000×10/100=400.
Therefore the cost of the scooter after the first year=4000-3600.
Similarly for the second year the cost would decrease by 10%.The cost would be reduce by 3600×10/100=360.Therfore the cost would be equal to 3600-360=3240.
The final answer is rupees 3240.

Answer 2

Cost Price of scooty = Rs. 40000
Given that value of scooty depreciates at rate of 10% per annum
Therefore, value of scooty depreciates after first year = 10% of CP
                                                                                      = 10/100 × 40000
                                                                                      =  Rs 4000 
Therefore, value of scooty after one year  =Rs 40000 - Rs 4000 = Rs 36000

Now, value of scooty depreciates after second year = 10% of new value
                                                                                  = 10/100 × 36000
                                                                                  = Rs 3600 
Therefore, value of scooty after two years  = Rs 36000 - Rs 3600 = Rs 32400
