Find :
(i) the sum.
(ii) the amount due at the end of 3 years and
at the same rate of interest compounded
annually.
(iii) the compound interest earned in 3 years.
​

Answer 1

i) SI=P*R*T/100
36000=P*10*2/100
36000*5=P
principal=₹1,80,000
ii) Amount=p(1+10/100)^3
A=180000(110/100)(110/100)(110/100)
A=₹239580
Amount=₹239580
iii)Compound Interest=Amount - principal
CI = 239580-180000
CI=₹59580
