Question

1. Find the rate of interest p.a. that will yield
600 as simple interest on 6000 in 2 years.
With this rate, find how much will * 8000
amount to in 2 years, with compound interest.​

Answer 1

Answer:

8820 rs.

Step-by-step explanation:

SI=600

P=6000

A=6000+600

=6600

600=(6000*r*2)/100

r=600*100/6000*2

r=5%

now,

In First year,

P=8000

T=1

r=5%

I=8000*5*1/100

I=400

THEREFORE,

IN SECOND YEAR,

P=8000+400

=8400

T=1

R=5%

I=8400*5*1/100

I=420

SO,AMOUNT AFTER 2 YEARS IS 8400+420 THAT IS 8820rs.
