Question

The difference in simple interest at 13% and 12% p.a. of a sum in one year is Rs. 110. Then the sum is​

Answer 1

$❥︎ANSWER</p><p></p><p>$

Let the amount be x,

then

simple interest for 1.5 years

=100PRT = 100x×12×1.5=10018x ---(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=0.0072150=20,833.33 RS.

∴ The total amount is 20,833.33 RS.
