Question

find the compound interest on rupees 9000 at 10% per annum for 3 year​

Answer 1

Answer:

Find the amount and compound interest on ₹ 9000 for 2 years 4 months at 10% per annum compounded annually.

Answer

Given:

Present value =₹ 9000

Interest rate =10% per annum

Time =2 years 4 months = (2+

3

1

) years= 7/3 years

To find the amount we have the formula,

Amount (A)=P(1+(r/100))

n

where P is the present value, r is the rate of interest and n is time in years.

Now substituting the values in above formula we get,

∴A=9000(1+10/100)

2

[1+(1/3×10)/100]

⇒A=9000(1+1/10)

2

(1+1/30)

⇒A=9000(11/10)

2

(31/30)

⇒A=9000×121/100×31/30=9×121×31/3

⇒A=₹ 11253

And Compound interest =A–P

=11253–6000=₹ 2253

Answer 2

Answer:

Compound Interest = Rupees 2253

Photodissociation, photolysis, or photodecomposition is a chemical reaction in which a chemical compound is broken down by photons. It is defined as the interaction of one or more photons with one target molecule. Photodissociation is not limited to visible light.
