Question

if ₹ 6000 amounts to ₹ 7620 in 9/2 years, find how much would it amount in 6 years at the same rate of interest

Answer 1

₹ 6000 amounts to ₹ 7620 in 9/2 years
amonut=7620
principal=6000
so simple interest 7620-6000=1620
time=9/2 years

rate of interst=[100*s.i/p*t]
                        =[100*1620i/6000*4.5]]=
 =6%

how much would it amount in 6 years at the same rate of interest
=amount =p +s.i
s.i=[p*r*t/100]
 s.i=[6000*6*6/100]
s.i=2160

=2160+6000
=8160
