sum of money in 2 years at 15% p.a. is
144. Find the sum.
I want clear explanation with steps ​

Answer 1

Step-by-step explanation:

Let principle be p

T=2years

R=15%

SI= P*R*T/100

=P*2*15/100

=3P/10amount for ci

= P(1+R/100)

=p(1+15/100)

=529/400pCI=529P/400-P

= 529-400/400

= 129/400PCI-SI

=144(given)129p/400-3p/10

=144129p-120p/400

=1449p/100=144p

=144*100/9p

=6400Therefore sum

=6400rs
