Step-by-step explanation:
1
st
year
Principal, P=Rs.5000
Time, T=1 year
Rate of interest ,R=6%
∴simple Interest, SI=
100
PTR
=
100
5000×10×6
=Rs.300
∴Amount=P+SI=Rs.5300
2nd year
Principal = Amount of 1st year=Rs.5300
Rate of interest =8%
Time =1 year
∴ Interest =
100
5300×1×8
=Rs.424
∴ Amount =Rs.(5300+424)=Rs.5724
The interest of 2nd year is the required compound interest. So, C.I=rs.424 and the required amount is Rs.5724
Step-by-step explanation:
Simple Interest = (P × R × T)/100
1. P = 1000, R = 3% , T = 2yr
S.I. = (1000×3×2)/100
= 6000/100
= 60
2. P = 5000, R = 7%, T = 2y
S.I. = (5000×7×2)/100
= 70000/100
= 700
Amount = Principal Amount + S.I.
= 5000 + 700
= 5700
