Question

At a certain rate of SI ₹4050 amounts to ₹4576.50 in 2 years .At the same rate of SI how much ₹1 lakh amount to in 3 years

Answer 1

4576.50-4050=526.50 si for 2 year
52650/100=4050×2×r/100
r=13/2=6.5%
si=100000×3×13/200=500×3×13=19500
so amount=100000+19500=119500
hope this is the answer
