Answer 1

Answer:

Answer =Principal =3200

Step-by-step explanation:

A=P X [1+R/100]n

3528=P X [1+5/100]2

3528=P X [105 /100]2

3528=P X [21/20]2

P=3528 X 20 square / 21 x 21

P=3200

Answer 2

Step-by-step explanation:

P=3,200;A=3,528;r=5%;n=?

A=P(1+100r)n

3,528=3,200(1+1005)n

or 3,2003,528=(100105)n

or (2021)2=(2021)n

∴n=2 years.
