Question

1. calculate the amount and the compound intrest on rupee 5000 in 2 years when the rate of intrest for successive years is 6% and 8% respectively.​

Answer 1

Answer:

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
