Question

the value of a machine depreciates by 10% annually if its present value is ₹100000 what will be its value after 2years

Answer 1

For these type of questions we generally use formula of compound interest .So formula is

A= P(1-rate/100)^t

According to your problem

We have to find A So

P = 100000 Rate = 10 t = 2

So put values on formula

A = 100000(1-10/100)^2

Opening the brackets and solving the values ....

A = 100000*9/10*9/10

Cut the zeros and we left with

A = 1000*81

So finally the answer is......

A = 81000

Therefore ....81000 will be amount after two years

Answer 2

Answer:

Step-by-step explanation:

Step-by-step explanation:

P=1,00,000

R=10%

T=2 Years

Depreciated Amount= P x (1-R/100) ²

=1,00,000 x (1-10/100)²

=1,00,000 x (9/10)²

=1,00,000 x 9/10 x 9/10

=1,00,000 x 0.9 x 0.9

=1,00,000 x 0.81

=       81,000
