Step-by-step explanation:

Present value = 4,50,000

Value after 1 year = 4,50,000- (20% of 4,50,000)

⇒ 4,50,000 - (20/100 * 4,50,000)

⇒ 4,50,000 - 90,000

⇒ 3,60,000

Value after 2 years = 3,60,000- (20% of 3,60,000)

⇒ 3,60,000- (20/100 * 3,60,000)

⇒ 3,60,000- 72,000

⇒ 2,88,000

Answer 2

Answer:

288000

Step-by-step explanation:

Every year, it decreases by 20%,  if present value is 450000,  next year it will decrease by 20%. That time,

price = 450000 - (20% of 450000)

        = 450000 - (20/100 * 450000)

        = 450000 - 90000

        = 360000

 After 1 more year, (2 year from beginning)

price = 360000 - (20% of 360000)

        = 360000 - (20/100 * 360000)

        = 360000 - 72000

        = 288000
