Answer 1

Price of the machine was 10,00,000 when Anil bought it.

Step-by-step explanation:

Sunil bought a 3 year old machine from Anil.

The price of machine at which Sunil bought = Rs. 7,29,000

Its value decreases by = 10 p.c.p.a.

Let the value of the machine when Anil purchased be 'x'.

Now we use the formula :

$\text{Current value}=p(1-r)^t$

p = purchased value, r = pcpa (10%) t = time (3 years)

7,29,000 = p(1-0.10)³

7,29,000 = p(0.9)³

7,29,000 = p × 0.729

p = $\frac{7,29,000}{0.729}$

p = 10,00,000 Rs.

Price of the machine was 10,00,000 when Anil bought it.

Answer 2

1000000

Step-by-step explanation:

Given : Sunil bought 3 years old machine

for ₹ 729000

It's value decreased by 10 % p.a

To find : Price of machine when anil bought it

A = p × ( 1 + R/100)^N

729000 = p × (1 + (-10)/100)³

729000 = p × ( 1 + (-1)/10)³

729000 = p × (9/10)³

729000 = p × 9/10 × 9/10 × 9/10

729000 = p × 729 /1000

729000/729 × 1000 = p

1000000 = p

Price of machine when Anil bought it = 1000000
