Answer:
1) P = 8000 , R = 5% , Time(n) = 3 years
Amount = P( 1+R/100)
= 8000(1+5/100)
=. 8000(105/100)
=. 8000(21/20)
=. 8000 x 21/20
=. 400 x 21
=. 8400.
Compound Interest = A - P
= 8400 - 8000
= 400.
2). P = 3200 , R = 25% , Time(n) = 3 years
Amount = P(1+R/100)
= 3200(1+25/100)
= 3200(125/100)
= 3200 x 25/20
= 160 x 25
= 4000.
Compound Interest = A - P
= 4000 - 3200
= 800.
