ANSWER
Simple Interest I=
100
PNR
Here for first year,
P=Rs.15,000
N=1 year
R=6 %
So, Interest at the end of 1st year I=
100
15,000×1×6
=Rs.900
And for second year,
P=Rs.15,000+Rs.900=Rs.15,900
N=1 year
R=8%
I=
100
15,900×1×8
=Rs.1272
And, for third year,
P=Rs.15,900+Rs.1,272=Rs.17,172
N=1 year
R=10%
I=
100
17,172×1×10
=Rs.1,717.2
So, total interest =Rs.900+Rs.1,272+Rs.1,717.2=Rs.3,889.20
Step-by-step explanation:
ok ok let's start
Ans==at first we have to find the amount ok
by this formula......
Amount =p(1+r/100)×(1+r/100)
=15000(1+6/100)×(1+8/100)
=15000×(1+3/50)×(1+2/25)
=15000×53/50×27/25
= ( now cancel which is cancelled ok)
=12×53×27
=17172
Now,
CI=A-P
=17172-15000
=2172..
