Answer 1

Answer:

8% p.a.

Step-by-step explanation:

principal amt. 3300/-

time(n). 4yrs

interest=?

AMT. 4356

* indicates multiply

/ indicates division

simple interest (SI)= PNI

SI=A-P

SI= 4356-3300

SI=1056

SI= PNI

1056=3300*4*i

1056=3300*4*I

1056/3300=4i

0.32= 4i

0.32/4= I

I=0.08

rate of interest is 8% p.a.
