Math Problem Statement
EXAMINATION-SET A 1. Find the interest on P 5,000 at 5% simple interest for 3 years. 2. What is the simple interest rate on P 60,000 for 6½ years if money earns P 5,000? 3. If P 3,000 is the interest at 5% after 5 months, how much was borrowed? 4. How long will it take for P 2,000 to become P3,500 at 5% simple interest? 5. Accumulate P10,000 at 10% for 5 years.
