2. Sonika bought a car for 5,50,000. The value of the car depreciates at the rate of 5% every six months
What is the value of the car after 2 years?
3. The price of silver at present is 8,000 per kg. Its price increases at the rate of 5% in the first year​

Answer 1

Answer =Rs. 447978.4375

2.

present price = 550000

the value of the car depreciates 5% after every six months

so, price of the car after six moths =550000-(5% of 550000)

= 550000 - 27500

= rs 522500

price ask the car after six months (six +six months=one year). = rs. 522500 -(5%of522500).

= 522500- 26125

=rs.496375

price of the car after more six months (one year plus six month). =496375- (5% of 496375)

=496375-24818.75

= 471556.25

price of the car after 6 months (after 2 years) =471556.25- (5% of 471556.25)

=471556.25- 23577.8125

=447978.4375

3. Answer = 8400 per kg

present price of silver 8000 per kg

its price increases at rate of 5% per year

price is silver after 1 year = 8000+5%of 8000

=8000+400

= 8400 per kg
