Step-by-step explanation:
S.I=₹80
R=4%
T=2 Year
C.I for 2 year at same rate =?
S.I=P×R×T/100
80=P×4×2/100
80=P×2/25
80=2P/25
P=80×25/2
P=40×25
P=₹1000
a/q
C.I=P[(1+r/100)^n-1]
=1000[(1+4/100)^2-1]
=1000[(25+1/25)^2-1]
=1000[(26/25)^2-1]
=1000[676/625-1]
=1000[676-625/625]
=1000×51/625
=408/5
=₹81.7
