Question

Savitha wants to purchase a laptop for which she borrowed rupees 40,000 from a bank at 10% per annum compounded annually for 3 years. Calculate the amount and compound interest to be paid by Savita after 3 years.​

Answer 1

Answer:

P=40000

R=10%

T=3YRS

A=P(R+1/100)

$a = p(r + 1 \div 100)n$

Step-by-step explanation:

a=40000(1+10/100)³

a=40000(11/10)³

a=40000*11/10*11/10*11/10

a=53240

amount=53240

ci=amount - principal

ci=53240-40000

ci=13240

Answer 2

Given:

P=40000

R=10%

T=3YRS

To Find:

Calculate the amount and compound interest to be paid by Savita after 3 years.​

Solution:

We know that,

A = $P(R+1/100)^{t}$

So,

A = 40000(1+10/100)³

  = 40000(11/10)³

  = 40000*11/10*11/10*11/10

  = 53240

∴Amount = 53240

∴Compound Interest = amount - principal

                                   = 53240-40000

                                   = 13240

Hence, Savita paid Rs.53240 and Rs.13240 as amount and compound interest respectively.
