Concept:The future value of an ordinary annuity is calculated using the formula: FV=P×r(1+r)n−1.Explanation:Given: P=500, r=0.14, n=7, and (1.14)7=2.5023.First, compute (1.14)7−1=2.5023−1=1.5023.Then, divide by r: 0.141.5023=10.7307142857.Finally, multiply by P: 500×10.7307142857=5365.35714285≈5365.35.Answer:Rs. 5365.35
