Question

find the compound interest on 6500 rupees for 2 years at 9% per annum

Answer 1

Answer :-

________________________

Principal ( p ) = Rs 6500

Time ( n ) = 2 years

Rate per annum ( r % ) = 9 %

•°• Compounded price = p ( 1 + r / 100 )ⁿ

= 6500 × ( 1 + 9 / 100 )²

= 6500 × 109 / 100 × 109 / 100

= 772265 / 100

= 7722.65

= Rs 7722.65

Therefore , Compound interest = Rs ( 7722.65 - 6500 )

= Rs 1222.65

Answer 2

Solution:-

Principal(p) =₹6500
Time(t)=2years
Rate(r)=9% per.annum

Amount=p(1+R/100)T

=6500(1+9/100)2

=6500(109/100)2

=6500×109/100×109/100
=₹7,722.65

C.I=₹(amount-principal)
=₹(7,722.65-6500)
=₹1,222.65(Answer)
