Answer 2

Answer:

(a) 720

(b) 75

(c) 600

(d) 400

Step-by-step explanation:

(a) Interest = (Principal×Rate×Time/100)

Principal=4,000 Rate 6% Time =3years

=(4,000×6×3/100)

=720

(b) Interest = (Principal×Rate×Time/100)

(5,000×0.5×3/100)

=75

(C) Interest = (Principal×Rate×Time/100)

=(3,000×10×2/100)

=600

(D) Interest = (Principal×Rate×Time/100)

=(20,000×20×1/100)

=400
