Question

A sum of 8000 is invested for 2 years at 10% per annum compounded interest
(A) interest for the first years

Answer 1

${\huge{\boxed{\sf{\green{Answer}}}}}$

So,the formula to find compound

interest is,

A = P(1+r/100)^n

for 1 yr,

A = P(1+r/100)^n

=8000(1+10/100)1 = 8000(11/10) = 8800

Amount = ₹8800

Compound interest =A - P

= 8800-8000

= 800rs

$\boxed{\bf{\purple{ So, \: interest \: for \: 1 yr\: is\: 800rs \: }}}$
