Question

on a certain sum, CI obtained after 8 years is rs. 5000 at 20% rate of CI . Find the CI obtained after 12 years​

Answer 1

Step-by-step explanation:

5000=p((1+20÷100)^8-1))______ (i)

x= p((1+20÷100)^12-1))-------------(ii)

Dividing(ii) by (i)

x/5000=p((6/5)^12-1))/p((6/5)^8-1)

x/5000=(8.9161-1)/(4.300-1)

=7.9161/3.300

x/5000= 2.4=2.4×5000

x= Rs 12000 Ans
