simple interest for 1.5 years

=

100

PRT

=

100

x×12×1.5

=

100

18x

---(1)

compound interest for 1 year

CI=x(1+r)=x(1+0.12)=1.12x

for neat 6 months

CI= 1.12x(1+0.06)=1.872x

net compound interest

CI=1.872x-x=0.1872x

now given CI-SI=150

0.1872x - 0.18x =150

0.0072x=150

x=

0.0072

150

=20,833.33 RS.

∴ The total amount is 20,833.33 RS.
