Answer 1

Answer:

• 1. Interest: $166.67

           Principal: $6,166.67

• 2. Interest: $200.00

            Principal: $5,200.00

Explanation:

1. $6000 for 50 days at 20% p.a

In 20% pa, pa means "per annum", i.e. "per year".

Assume simple interest:

• Principal: $6,000

• interest: 20% pa

• time = 50 days

Interest:

• Interest = Principal × number of days × annual rate / 360

• Interest = $6,000 × 50 × 20% / 360 = $166.67

Principal = principal + interest = $6,000 + $166.67 = $6,166.67

2. $5000 for 5 months at 0.8% per month

Assume, again, simple interest.

• Principal: $5,000

• interest: 0.80% per month

• time = 5 months

Interest:

• Interest = Principal × number of months × montly rate

• Interest = $5,000 × 5 × 0.80%  = $200.00

Principal = principal + interest = $5,000 + $200.00 = $5,200

You can see that the accrued interests depend on the principal, the interest rate, and the time.
