Answer:_______________

A motorcycle was bought at 68101 . The value depreciated at the rate of 2% p.a. find the value after one year.

Answer: 66739

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 68101

n = 1 year

r = 2%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 68101[ $\frac{1-(2}{100)}$ ]¹

= 68101[1-0.02]¹

= 68101 x 0.98¹

= 66739

A motorcycle was bought at 71293 . The value depreciated at the rate of 6% p.a. find the value after one year.

Answer: 67015

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 71293

n = 1 year

r = 6%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 71293[ $\frac{1-(6}{100)}$ ]¹

= 71293[1-0.06]¹

= 71293 x 0.94¹

= 67015

A motorcycle was bought at 73711 . The value depreciated at the rate of 2% p.a. find the value after one year.

Answer: 72237

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 73711

n = 1 year

r = 2%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 73711[ $\frac{1-(2}{100)}$ ]¹

= 73711[1-0.02]¹

= 73711 x 0.98¹

= 72237

A motorcycle was bought at 70077 . The value depreciated at the rate of 5% p.a. find the value after one year.

Answer: 66573

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 70077

n = 1 year

r = 5%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 70077[ $\frac{1-(5}{100)}$ ]¹

= 70077[1-0.05]¹

= 70077 x 0.95¹

= 66573

A motorcycle was bought at 70341 . The value depreciated at the rate of 6% p.a. find the value after one year.

Answer: 66121

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 70341

n = 1 year

r = 6%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 70341[ $\frac{1-(6}{100)}$ ]¹

= 70341[1-0.06]¹

= 70341 x 0.94¹

= 66121

= 77421 x 0.95¹

= 73550

A motorcycle was bought at 75930 . The value depreciated at the rate of 3% p.a. find the value after one year.

Answer: 73652

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 75930

n = 1 year

r = 3%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 75930[ $\frac{1-(3}{100)}$ ]¹

= 75930[1-0.03]¹

= 75930 x 0.97¹

= 73652

A motorcycle was bought at 67994 . The value depreciated at the rate of 8% p.a. find the value after one year.

Answer: 62554

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 67994

n = 1 year

r = 8%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 67994[ $\frac{1-(8}{100)}$ ]¹

= 67994[1-0.08]¹

= 67994 x 0.92¹

= 62554

A motorcycle was bought at 79586 . The value depreciated at the rate of 7% p.a. find the value after one year.

Answer: 74015

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 79586

n = 1 year

r = 7%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 79586[ $\frac{1-(7}{100)}$ ]¹

= 79586[1-0.07]¹

= 79586 x 0.93¹

= 74015
