Principale 5000 Rate of interest =8p.c.p.a.A interest =Rs 1200 period =?​

Answer 1

ATQ

P=5000

R=8%

I=1200

FIND TIME?

=A= P+ C. I.

=5000+1200=6200

=6200 AMOUNT

A=P(1+R/100)^N

6200=5000(1+8/100)^N

=6200/5000=(1*100/1*100+8/100)^N

=27/25= (108/100) ^N

=√27/√25=(27/25) ^N

=(5.196) ^2=27/25

=2=N
