Question

In how many years Rs 13000
become 17303 at 10% per
annum compounded yearly​

Answer 1

Step-by-step explanation:

Let time is 3 year

now

take

P = 1000

then according to 10% CI after 3 years

A = 1331

ao now if 1000 is equal to 13000 then 17303 must be equal to 1331

1000×13= 13000

1331×13= 17303

hence it is prooved that time is 3 years

or another method

13000÷13=1000

17303÷13=1331

in only 3 years 1000 can be 1331 at 10% rate

so the time is 3 years

Answer 2

Answer:

In 3 years Rs 13000 become 17303 at 10% per annum compounded yearly​.

Step-by-step explanation:

Initial amount(p) = Rs 13000.

Final amount(i) = Rs 17303.

Interest rate(r) = 10%.

n = time .

Compound interest (i) = p(1+(r/100) ∧ n .

17303 = 13000 ( 1 + (10/100) ) ∧ n .

or , (11/10) ∧ n = (17303/13000).

or , (11/10) ∧ n = (1331/1000).

or , (11/10) ∧ n = (11/10) ∧ 3.

or , n = 3.

In 3 years Rs 13000 become 17303 at 10% per annum compounded yearly​.
