Answer:_______________

A motorcycle was bought at 78807 . The value depreciated at the rate of 6% p.a. find the value after one year.

Answer: 74079

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 78807

n = 1 year

r = 6%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 78807[ $\frac{1-(6}{100)}$ ]¹

= 78807[1-0.06]¹

= 78807 x 0.94¹

= 74079

A motorcycle was bought at 78276 . The value depreciated at the rate of 4% p.a. find the value after one year.

Answer: 75145

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 78276

n = 1 year

r = 4%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 78276[ $\frac{1-(4}{100)}$ ]¹

= 78276[1-0.04]¹

= 78276 x 0.96¹

= 75145

A motorcycle was bought at 77154 . The value depreciated at the rate of 2% p.a. find the value after one year.

Answer: 75611

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 77154

n = 1 year

r = 2%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 77154[ $\frac{1-(2}{100)}$ ]¹

= 77154[1-0.02]¹

= 77154 x 0.98¹

= 75611

A motorcycle was bought at 53929 . The value depreciated at the rate of 7% p.a. find the value after one year.

Answer: 50154

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 53929

n = 1 year

r = 7%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 53929[ $\frac{1-(7}{100)}$ ]¹

= 53929[1-0.07]¹

= 53929 x 0.93¹

= 50154

A motorcycle was bought at 63293 . The value depreciated at the rate of 7% p.a. find the value after one year.

Answer: 58862

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 63293

n = 1 year

r = 7%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 63293[ $\frac{1-(7}{100)}$ ]¹

= 63293[1-0.07]¹

= 63293 x 0.93¹

= 58862

n = 1 year

r = 5%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 75961[ $\frac{1-(5}{100)}$ ]¹

= 75961[1-0.05]¹

= 75961 x 0.95¹

= 72163

A motorcycle was bought at 62258 . The value depreciated at the rate of 5% p.a. find the value after one year.

Answer: 59145

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 62258

n = 1 year

A motorcycle was bought at 73195 . The value depreciated at the rate of 8% p.a. find the value after one year.

Answer: 67339

SOLUTION 1 :

Given :

The value of motorcycle depreciates

P = 73195

n = 1 year

r = 8%

A = P[ $\frac{1-(r}{100)}$ ]ⁿ

= 73195[ $\frac{1-(8}{100)}$ ]¹

= 73195[1-0.08]¹

= 73195 x 0.92¹

= 67339
