Question

find the compound interest on 2500 for 3years at 10% per annum co.mpounded annually​

Answer 1

Step-by-step explanation:

Present value= ₹ 2500

Interest rate= 10% per annum

Time=2 years

To find the amount we have the formula,

Amount (A) = P (1+(R/100))n

Where P is present value, r is rate of interest, n is time in years.

Now substituting the values in above formula we get,

∴ A = 2500 (1 + 10/100)2

⇒ A = 2500 (11/10)2

⇒ A = 2500 (121/100)

⇒ A = 25 (121)

⇒ A = ₹ 3025

∴ Compound interest = A – P = 3025 – 2500= ₹ 525

Answer 2

Solution

Present value=₹2500

Interest rate=10% per annum

Time=2 years

To find the amount we have the formula,

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

n

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

Now substituting the values in above formula we get,

∴A=2500(1+10/100)

2

⇒A=2500(11/10)

2

⇒A=2500(121/100)

⇒A=25(121)

⇒A=₹3025

Now,

∴ Compound interest = A–P

=3025–2500=₹525
