Question

Dinah purchased a scooter for rupees 24000 the value of the scooter is depreciating at the rate of 5%per annum .Calculate its value after 3 years

Answer 1

Heya ☺

Given that

P = ₹24,000

R = 5 % p.a.

T = 3 years

Solution

Cost of scooter after 3 years = P(1-R/100)^n

= 24,000(1-5/100)^3

= 24,000(100-5/100)^3

= 24,000(95/100)^3

= 24,000(19/20)^3

= 24,000 × 5,491/8,000

= ₹16,473





Thanks

Answer 2

Answer:

Rs 20577

Step-by-step explanation:

Since:

Value of scooter = 24000

There is 5%  decrease in value of Scooter every year

The 5 % of 24000 = (5/100) × 24000

                                         = 1200

The value of scooter after one year = 24000 - 1200 = 22800

Similarly,

The 5 % of 22800 = (5/100) × 22800 = 1140

Hence, the value of scooter after Two years = 22800 - 1140 = 21660

The 5 % of 21660 = (5/100) × 21660 = 1083

Hence,

The value of Scooter after three years = 21660 - 1083  

The value of Scooter after three years   = 20577
