Question

on what sum will the ci fir 2 years at 5 percent p.a be rs 1230​

Answer 1

CI for 2 years is=615 Rs.

SI for 2 years is=600 Rs.

Difference of CI and SI is=615–600

=15 Rs.

If 2 years SI is 600 Rs.,then 1 year SI is=600/2

=300

15 is the what percent of 300.

=15*100/300

=15/3

=5%

If 5% is 300 Rs. then 100% of that principal.

=300*100/5

=60*100

=6000 Rs.

So the principal is 6000 Rs.
