Question

the value of a residential flat constructed at a cost of rs.100000 is deprecating at the rate of 10% per annum. What will be its value 3 years after construction?

Answer 1

Answer:

Step-by-step explanation:

Principal = Rs. 10,000

Rate= 10%

time= 3 years

therefore, P (1- r/100) to the power 3

=10,000 (1- 10/100) to the power 3

= 10,000 x 90 x 90 x90/ 100 x 100 x 100

= Rs. 7290

Ans: Rs 7290

Answer 2

Answer:

The value 3 years after construction is Rs. 72,900

Step-by-step explanation:

Given:

Principal = Rs. 100000

Rate= 10%

time= 3 years

To find: value after 3 years of construction

Solution:

we know,

P$(1 - \frac{P}{100} )^{n}$ Here, P = Principle and n = number

= 100000 $( 1 - \frac{10}{100} )^{3}$

= 100000 x 90/100 x 90/100 x90/ 100

= 72900

Hence, The value after 3 years of construction is Rs 72,900. Ans
