Simple interest games
Simple interest
SI = P × R × T ÷ 100 — P = principal (money lent or borrowed), R = rate % per year, T = time in years.
Amount = P + SI. Turned around: R = SI × 100 ÷ (P × T), T = SI × 100 ÷ (P × R), P = SI × 100 ÷ (R × T).
Months: write T in years — 6 months = ½ year, 9 months = ¾ year.
For Class 7 and 8. All answers are computed by a program.
